Installation icon Flags 01

Parts

  • 1 Vinyl Panel Pet Door
  • 1 Weatherstrip Seal
  • 1 Center Post Weather Seal Draft Stopper

Tools

  • Flathead screwdriver
  • #2 Philips head screwdriver
  • Non-metal hammer
  • Scissors

Please read instructions & notes thoroughly before installation. If your panel arrived in two pieces, see our instructions for sectionals.

Step 1 Loosen Height Adjustment Locks

  • Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.
  • Horizontal Cross pieces have Edge Guides on each end. Carefully remove these parts and keep them together. This will help with assembly and orientation and when reassembling the piece.

Step 2 Insert Panel Into Track

  • Insert the panel into the upper track of your door frame, push the panel into the spring mechanism, then swing the bottom of the panel up and over the threshold into the lower track rail.
  • If you can’t clear the track, try swinging in from the outside, as the outside track wall may be shorter. If the panel still doesn’t fit, see the FAQ for guidance.

Step 3 Apply Weatherstrip

  • Once you are confident that the panel fits, remove the panel from the track and lay it on its side on the ground.
  • Apply the foam weatherstrip seal by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides and trim to fit with scissors.

Step 4 Place Panel In Track

  • Place the panel back into the sliding glass door, then tighten the height adjustment locks to lock it in place.

Step 5 Install the Draft Stopper

  • The center post weather seal strip (draft stopper) should be installed on the inside of the home.
  • It can install on either the back edge of the sliding door panel or the leading edge of the stationary panel.
  • This strip prevents air from leaking between the sliding glass door and the stationary panel.
  • Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
  • Repeat step two to install the panel in your track.

Please read instructions & notes thoroughly before installation. If you need to adjust the step-over height, complete steps A-C before installing the panel in your track.

Step 1 Assemble the Panel

  • Align the aluminum connectors extending from the bottom flap panel section with the top glass panel section.
  • Press the aluminum connectors into the holes at the bottom of the top glass panel section.
  • Ensure locking cover & height adjustment locks are on the same side!

FAQ

What if my panel is slightly too tall?

You can trim up to 5/16" off the spring-loaded adjustment piece at the top. Remove the adjustment piece with a #2 Philips head screwdriver and use scissors to cut down the flanges. Be careful not to cut too low.

What if my panel is slightly too short?

We ofer height extensions that will add 1 1/2" to the top of the panel that you slide into the channel at the top. These are made from the same vinyl as the panel so the color will match exactly. If the extension makes the panel feel unstable, you can secure it with screws.

What if the panel is wobbling slightly back and forth?

If your track is wider than 1 1/2", you can use small wooden shims or extra weather-stripping to fill the gap inside the top and bottom tracks. By placing the material inside the tracks you won't be able to see it, but it will stabilize the panel.

Locking Your Door

Since you cannot lock your sliding glass door to the panel, we have provided you with a sliding door clamp lock to secure your home.

Installing the sliding door clamp:

This clamp as a screw that tightens by hand to prevent the sliding door from moving beyond the clamp's placement. For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the door's raised track.

If you aren't able to use the lock that comes with the panel:

A great alternative to locking your sliding glass door is a Charley bar or dowel. Both block the slider from opening. When engaged, you cannot pull the sliding door away from the pet door panel.

FAQ

What if my panel is slightly too tall?

You can trim up to 3/4" off the spring-loaded adjustment piece at the top. This can be done by removing the adjustment piece with a #2 Phillips head screwdriver and cutting down the flanges. Be careful not to cut too low of you will not be able to put the top back on.

What if my panel is slightly too short?

We offer height extensions that will add 3/4" to the top of the panel that you slide into the channel at the top. These are made from the same aluminum as the panel so you can match the color.

You can also make your extension out of 1" wood (which is 3/4" thick), such as a 1x3 if you need more than 3/4" in height.

Cut it to the same width as the panel and slide it into the channel at the top. Paint the wood to match your frame color. If the extension makes the panel feel unstable, you can secure it with screws.

What if hardware for the locking latch is preventing the door from sealing properly?

You might be able to remove the hardware, as in some cases they are only held in place with a couple of screws.

If you are not able to remove it you can try installing the panel on the stationary side as mentioned on page.

If neither of those choices works, you can try to shim the panel out so that it is even with the face of the lock. Depending on how far it sticks out you might be able to use a thicker foam weatherstripping or a small piece of wood between the panel and wall jamb.

My slider isn't closing evenly against the panel?

Your slider may not be level, which can happen in older houses. In that case, you may be able to adjust the wheels on the slider enough to line it back up. It will depend on your door, but you should be able to adjust a screw near the bottom of the door.

Turning the screw will adjust the wheels slightly. If the slider is level then it could be an issue with the metal height adjustment lock at the top of the panel. You can also use a rubber mallet to tap the curve into a straight line.

If the height adjustment lock is hitting the edge this can mean that the bottom of the panel is going further into the jamb that it can at the top. A gap appears that gets wider as you go down the panel. You can use wood shims or weatherstripping in the jamb to push out the bottom of the panel.

What if the panel is wobbling slightly back and forth?

If your track is wider than 1" you can use small wooden shims or extra weatherstripping to fill in the gap inside the top and bottom tracks. By placing the material inside the tracks you won't be able to see it, but it will stabilize the panel. You might also try semi-permanently installing the pet door.

The slider is on the outside track? How do I lock it?

This can cause an issue if you are trying to lock the door since the clamp lock, Charley bar, or dowel in the track won't really work. In this case, you can use a foot lock. The downside is that you have to drill that into the front end of the stationary panel frame as well as a small hole in the sliding door frame.

Depending on the handle of your slider, you might be able to put a Charley bar between the handle and the edge of the stationary. The slider would then push against the pet door and prevent someone from opening your door.

Alternatively, you can also try installing the pet door between your stationary glass and wall.

There is a large ste-down going out/coming in for the pet?

In this case, you can use a ramp or some small steps to minimize the height of the drop. You'll want the distance between the top of the flap and the ground to allow your pet to go through your flap without ducking or hitting their back.

What if I have an alarm system?

The alarm company might be able to come out and move the sensor for you. So instead of one part being on the door and the other on the jamb, you would end up having one side on the panel that matched up with the one on the sliding door.

As there are many different types of alarm configurations we would recommend that you always consult the alarm security company first to discuss your options.

FAQ

Is this the same as the Thermo Panel 3e sliding glass dog door insert?

This is very similar in that it has the same height ranges, flap sizes, and Low-e glass. However, this vinyl panel is specifically made to fit better in the wider vinyl slider tracks. Read about the differences between vinyl and aluminum pet door panels here.

Will it fit all vinyl sliding glass doors?

This panel fits doors that have a recessed track at least 1-1/2" wide, with a rail in the bottom that is about the size of a pencil. The panel is made with a small channel that will case over that little rail

Does the flap lock?

The vinyl sliding dog door panel comes with a secure locking cover to block access to the flap when needed.

Can an intruder remove the sliding glass door dog door from the outside?

No. The thumbscrews on the sliding glass door dog door insert are on the inside of the house so you cannot loosen them from the outside.

Does the doggy door lock?

We do include a c-clamp lock to lock the panel in place in your slider track. However, the sliding door dog door panel does not mate with your existing sliding door lock. You can also use a Charley bar or wooden dowel for additional security.

Does this vinyl pet patio door panel insulate well?

Yes, the vinyl sliding pet door insulates very well. The flap is lined with magnets on three sides to stay shut in winds up to 50mph. The glass in the sliding pet door panel is Low-E for maximum insulation.

How do I measure for a dog door for sliding glass doors?

You will want to measure from the deepest part (down past the little metal rail) in the bottom, then all the way up to the deepest part inside the top track for your track height.

Does the sliding door dog door insert come in any color other than white?

No, but the vinyl sliding glass pet door can be painted to match your home.

What if my track is wider than 1-1/2"?

It will still work if your track is wider, but if the channel in the bottom, top, or side measures less than that you will not be able to fit it into place properly.

Does your door have to be vinyl?

No, this can work for aluminum sliders with tracks at least 1.5" thick.

Is the flap flexible?

It is flexible, but since it is two pieces sandwiched together it is a little stiffer and heavier than the more economical vinyl flaps.

Is the flap clear?

It is a little foggy, but it is see-through so it's easy for pets to use.

Will this form condensation like the aluminum panels?

Nope! One of the benefits of a vinyl pet door for vinyl sliding doors is that it won't "sweat" in cold weather the way aluminum panels can.

My sliding door track has a triangular guide rail. Will this pet door still work?

Some sliding glass door tracks have a triangle-shaped guide rail instead of a cylindrical pencil rail running along the middle. This pet door panel has an arch along the bottom that is designed to sit on top of a cylindrical pencil rail. Pencil rails are shorter in height than triangular guide rails, which means that the pet door panel would wobble on top of it rather than sitting flush with the rest of the track. To accommodate the pet door panel you will need to build up the sides of the triangular guide rail so that the tip is less than ¼” tall. Please reach out to customer service if you have any questions about this process.

Will this panel work if my sliding glass door has a buried track?

Some sliding glass doors have buried tracks. Since this panel has an arch along the bottom that is designed to sit on top of a pencil rail, it will not be secure in a slider with a buried track without modifications. We recommend securing the panel to the track wall with L brackets or toenailing it to the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss your options for a buried track.

I have a hurricane patio door. Will this pet door work for me?

Hurricane door track styles vary widely, so they are case-by-case. Please reach out to customer service to discuss your pet door options for your sliding door.

Will this pet door work with Anderson and Pella sliding doors?

Anderson and Pella sliding glass doors have an inner track wall but no outer track wall. Additionally, the pencil rail is on the outer edge of the track rather than in the middle. Since this pet door panel is designed to sit between two track walls and on top of a centered pencil rail, it cannot be installed in Anderson or Pella doors without modifications. We recommend building out your track and using L brackets or toenailing to secure the bottom of the panel to the inner track wall. Building out the track means adding a piece of wood or vinyl that is the same height as the pencil rail to the space next to the pencil rail. This creates a flat surface for the pet door panel to sit on. Next, you will need to secure the panel to the track wall. To do this, you can use L brackets or you can toenail the panel into the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss this process or different options for an Anderson or Pella sliding door.

Can I install this pet door if my sliders meet in the middle?

Yes! You can use this guide to find out how.

Needs Improvement

It's a doggie door. No way it's good for weather. Condensation builds up on inside window. Wind blows through gaps at the corners of the window and the flap. Rain comes through the door flap when windy. Very likely that this will be unusable in the summer and winter months.

Not happy

Not good. For what it cost I expected better quality. The flap doesn’t close properly all the time. The dogs don’t like the way it slams. I have another dog door in another part of the house that they zip in and out. It’s came w the door. This was way too much money. I should have gone w one of the less expensive doors and probably gotten something better

LOVE LOVE LOVE our new Vinyl Dog Door!!!

If we could give more than 5 stars we would. Can’t believe we waited so long to purchase. The installation could not have been easier. The cold air is out, the warm air in and all 3 dogs learned how to use it in less than 20 minutes. Once one dog figured out, he showed the others. This is a VERY high quality door. Customer Service is wonderful. The instructions are simple and straightforward. For reference we purchased the Large Vinyl Door and have a Labradoodle, Labrador-Golden Retriever and a Boxer Mix.

Terrible quality and won’t fully refund

We ordered the sliding g glass door pet door at near $600 because wanted a quality door. The door arrived with large air gaps due to poor construction. They picked that one and sent new one. New door had same problem so we sent back and asked for refund. I’m this later, still no refund. They kept telling us they had refunded our credit card but in fact had not. For some reason, they said they refunded a large portion in one transaction and another for $66. We finally received a $500 refund but they never refunded the $66. I cannot recommend doing business with this company.

So Pleased

I rarely write reviews but I am so happy with this dog door I wanted to submit a review. It was very easy for me to install by myself and while I thought the XL would be too small for my 2 Bouvier des Flanders it turns out to be the perfect size. The other dog doors I have used gapped terribly after a few months so I was especially interested in the all sides encased in metal of this door. My dogs took to it immediately and it looks so nice in my sliding door. I purchased a door lock that stays in place permanently so we don't use this door other than for the dog door as the remaining opening is pretty small.

  • Insert the panel into the upper track of your door frame, push the panel into the spring mechanism, then swing the bottom of the panel up and over the threshold into the lower track rail.
  • If you can’t clear the track, try swinging in from the outside, as the outside track wall may be shorter. If the panel still doesn’t fit, see the FAQ for guidance.

Step 4 Apply Weatherstrip

  • Once you are confident that the panel fits, remove the panel from the track and lay it on its side on the ground.
  • Apply the foam weatherstrip seal by peeling back the paper and exposing the adhesive. Unroll it along the edge of the panel, pressing to ensure it adheres. Install on both sides and trim to fit with scissors.

Step 5 Place Panel In Track

  • Place the panel back into the sliding glass door, then tighten the height adjustment locks to lock it in place.

Step 6 Install the Draft Stopper

  • The center post weather seal strip (draft stopper) should be installed on the inside of the home.
  • It can install on either the back edge of the sliding door panel or the leading edge of the stationary panel.
  • This strip prevents air from leaking between the sliding glass door and the stationary panel.
  • Trim with scissors as needed. Clean the edge of your patio door with rubbing alcohol before installing to assure a good seal.
  • Repeat step two to install the panel in your track.

FAQ

What if my panel is slightly too tall?

You can trim up to 5/16" off the spring-loaded adjustment piece at the top. Remove the adjustment piece with a #2 Philips head screwdriver and use scissors to cut down the flanges. Be careful not to cut too low.

What if my panel is slightly too short?

We ofer height extensions that will add 1 1/2" to the top of the panel that you slide into the channel at the top. These are made from the same vinyl as the panel so the color will match exactly. If the extension makes the panel feel unstable, you can secure it with screws.

What if the panel is wobbling slightly back and forth?

If your track is wider than 1 1/2", you can use small wooden shims or extra weather-stripping to fill the gap inside the top and bottom tracks. By placing the material inside the tracks you won't be able to see it, but it will stabilize the panel.

Locking Your Door

Since you cannot lock your sliding glass door to the panel, we have provided you with a sliding door clamp lock to secure your home.

Installing the sliding door clamp:

This clamp as a screw that tightens by hand to prevent the sliding door from moving beyond the clamp's placement. For doors manufactured with the glass slider on the inside track, the lock can usually be installed on the door's raised track.

If you aren't able to use the lock that comes with the panel:

A great alternative to locking your sliding glass door is a Charley bar or dowel. Both block the slider from opening. When engaged, you cannot pull the sliding door away from the pet door panel.

FAQ

What if my panel is slightly too tall?

You can trim up to 3/4" off the spring-loaded adjustment piece at the top. This can be done by removing the adjustment piece with a #2 Phillips head screwdriver and cutting down the flanges. Be careful not to cut too low of you will not be able to put the top back on.

What if my panel is slightly too short?

We offer height extensions that will add 3/4" to the top of the panel that you slide into the channel at the top. These are made from the same aluminum as the panel so you can match the color.

You can also make your extension out of 1" wood (which is 3/4" thick), such as a 1x3 if you need more than 3/4" in height.

Cut it to the same width as the panel and slide it into the channel at the top. Paint the wood to match your frame color. If the extension makes the panel feel unstable, you can secure it with screws.

What if hardware for the locking latch is preventing the door from sealing properly?

You might be able to remove the hardware, as in some cases they are only held in place with a couple of screws.

If you are not able to remove it you can try installing the panel on the stationary side as mentioned on page.

If neither of those choices works, you can try to shim the panel out so that it is even with the face of the lock. Depending on how far it sticks out you might be able to use a thicker foam weatherstripping or a small piece of wood between the panel and wall jamb.

My slider isn't closing evenly against the panel?

Your slider may not be level, which can happen in older houses. In that case, you may be able to adjust the wheels on the slider enough to line it back up. It will depend on your door, but you should be able to adjust a screw near the bottom of the door.

Turning the screw will adjust the wheels slightly. If the slider is level then it could be an issue with the metal height adjustment lock at the top of the panel. You can also use a rubber mallet to tap the curve into a straight line.

If the height adjustment lock is hitting the edge this can mean that the bottom of the panel is going further into the jamb that it can at the top. A gap appears that gets wider as you go down the panel. You can use wood shims or weatherstripping in the jamb to push out the bottom of the panel.

What if the panel is wobbling slightly back and forth?

If your track is wider than 1" you can use small wooden shims or extra weatherstripping to fill in the gap inside the top and bottom tracks. By placing the material inside the tracks you won't be able to see it, but it will stabilize the panel. You might also try semi-permanently installing the pet door.

The slider is on the outside track? How do I lock it?

This can cause an issue if you are trying to lock the door since the clamp lock, Charley bar, or dowel in the track won't really work. In this case, you can use a foot lock. The downside is that you have to drill that into the front end of the stationary panel frame as well as a small hole in the sliding door frame.

Depending on the handle of your slider, you might be able to put a Charley bar between the handle and the edge of the stationary. The slider would then push against the pet door and prevent someone from opening your door.

Alternatively, you can also try installing the pet door between your stationary glass and wall.

There is a large ste-down going out/coming in for the pet?

In this case, you can use a ramp or some small steps to minimize the height of the drop. You'll want the distance between the top of the flap and the ground to allow your pet to go through your flap without ducking or hitting their back.

What if I have an alarm system?

The alarm company might be able to come out and move the sensor for you. So instead of one part being on the door and the other on the jamb, you would end up having one side on the panel that matched up with the one on the sliding door.

As there are many different types of alarm configurations we would recommend that you always consult the alarm security company first to discuss your options.

FAQ

Is this the same as the Thermo Panel 3e sliding glass dog door insert?

This is very similar in that it has the same height ranges, flap sizes, and Low-e glass. However, this vinyl panel is specifically made to fit better in the wider vinyl slider tracks. Read about the differences between vinyl and aluminum pet door panels here.

Will it fit all vinyl sliding glass doors?

This panel fits doors that have a recessed track at least 1-1/2" wide, with a rail in the bottom that is about the size of a pencil. The panel is made with a small channel that will case over that little rail

Does the flap lock?

The vinyl sliding dog door panel comes with a secure locking cover to block access to the flap when needed.

Can an intruder remove the sliding glass door dog door from the outside?

No. The thumbscrews on the sliding glass door dog door insert are on the inside of the house so you cannot loosen them from the outside.

Does the doggy door lock?

We do include a c-clamp lock to lock the panel in place in your slider track. However, the sliding door dog door panel does not mate with your existing sliding door lock. You can also use a Charley bar or wooden dowel for additional security.

Does this vinyl pet patio door panel insulate well?

Yes, the vinyl sliding pet door insulates very well. The flap is lined with magnets on three sides to stay shut in winds up to 50mph. The glass in the sliding pet door panel is Low-E for maximum insulation.

How do I measure for a dog door for sliding glass doors?

You will want to measure from the deepest part (down past the little metal rail) in the bottom, then all the way up to the deepest part inside the top track for your track height.

Does the sliding door dog door insert come in any color other than white?

No, but the vinyl sliding glass pet door can be painted to match your home.

What if my track is wider than 1-1/2"?

It will still work if your track is wider, but if the channel in the bottom, top, or side measures less than that you will not be able to fit it into place properly.

Does your door have to be vinyl?

No, this can work for aluminum sliders with tracks at least 1.5" thick.

Is the flap flexible?

It is flexible, but since it is two pieces sandwiched together it is a little stiffer and heavier than the more economical vinyl flaps.

Is the flap clear?

It is a little foggy, but it is see-through so it's easy for pets to use.

Will this form condensation like the aluminum panels?

Nope! One of the benefits of a vinyl pet door for vinyl sliding doors is that it won't "sweat" in cold weather the way aluminum panels can.

My sliding door track has a triangular guide rail. Will this pet door still work?

Some sliding glass door tracks have a triangle-shaped guide rail instead of a cylindrical pencil rail running along the middle. This pet door panel has an arch along the bottom that is designed to sit on top of a cylindrical pencil rail. Pencil rails are shorter in height than triangular guide rails, which means that the pet door panel would wobble on top of it rather than sitting flush with the rest of the track. To accommodate the pet door panel you will need to build up the sides of the triangular guide rail so that the tip is less than ¼” tall. Please reach out to customer service if you have any questions about this process.

Will this panel work if my sliding glass door has a buried track?

Some sliding glass doors have buried tracks. Since this panel has an arch along the bottom that is designed to sit on top of a pencil rail, it will not be secure in a slider with a buried track without modifications. We recommend securing the panel to the track wall with L brackets or toenailing it to the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss your options for a buried track.

I have a hurricane patio door. Will this pet door work for me?

Hurricane door track styles vary widely, so they are case-by-case. Please reach out to customer service to discuss your pet door options for your sliding door.

Will this pet door work with Anderson and Pella sliding doors?

Anderson and Pella sliding glass doors have an inner track wall but no outer track wall. Additionally, the pencil rail is on the outer edge of the track rather than in the middle. Since this pet door panel is designed to sit between two track walls and on top of a centered pencil rail, it cannot be installed in Anderson or Pella doors without modifications. We recommend building out your track and using L brackets or toenailing to secure the bottom of the panel to the inner track wall. Building out the track means adding a piece of wood or vinyl that is the same height as the pencil rail to the space next to the pencil rail. This creates a flat surface for the pet door panel to sit on. Next, you will need to secure the panel to the track wall. To do this, you can use L brackets or you can toenail the panel into the track wall. Toenailing is the process of fastening the panel to the track by driving a nail at roughly a 45-degree angle into the panel and through the track wall. Please note that these modifications result in a semi-permanent installation. If you needed to remove the panel in the future you would first have to remove the L brackets or nails. Additionally, please note that this process would leave holes in the pet door panel and it would no longer be returnable. Please reach out to customer service to further discuss this process or different options for an Anderson or Pella sliding door.

Can I install this pet door if my sliders meet in the middle?

Yes! You can use this guide to find out how.

Needs Improvement

It's a doggie door. No way it's good for weather. Condensation builds up on inside window. Wind blows through gaps at the corners of the window and the flap. Rain comes through the door flap when windy. Very likely that this will be unusable in the summer and winter months.

Not happy

Not good. For what it cost I expected better quality. The flap doesn’t close properly all the time. The dogs don’t like the way it slams. I have another dog door in another part of the house that they zip in and out. It’s came w the door. This was way too much money. I should have gone w one of the less expensive doors and probably gotten something better

LOVE LOVE LOVE our new Vinyl Dog Door!!!

If we could give more than 5 stars we would. Can’t believe we waited so long to purchase. The installation could not have been easier. The cold air is out, the warm air in and all 3 dogs learned how to use it in less than 20 minutes. Once one dog figured out, he showed the others. This is a VERY high quality door. Customer Service is wonderful. The instructions are simple and straightforward. For reference we purchased the Large Vinyl Door and have a Labradoodle, Labrador-Golden Retriever and a Boxer Mix.

Terrible quality and won’t fully refund

We ordered the sliding g glass door pet door at near $600 because wanted a quality door. The door arrived with large air gaps due to poor construction. They picked that one and sent new one. New door had same problem so we sent back and asked for refund. I’m this later, still no refund. They kept telling us they had refunded our credit card but in fact had not. For some reason, they said they refunded a large portion in one transaction and another for $66. We finally received a $500 refund but they never refunded the $66. I cannot recommend doing business with this company.

So Pleased

I rarely write reviews but I am so happy with this dog door I wanted to submit a review. It was very easy for me to install by myself and while I thought the XL would be too small for my 2 Bouvier des Flanders it turns out to be the perfect size. The other dog doors I have used gapped terribly after a few months so I was especially interested in the all sides encased in metal of this door. My dogs took to it immediately and it looks so nice in my sliding door. I purchased a door lock that stays in place permanently so we don't use this door other than for the dog door as the remaining opening is pretty small.
