Parts

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

Tools

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

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

Step 1 Loosen Height Adjustment Locks

  • Note: 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.
  • Loosen the height adjustment locks at the top of the panel. This allows the spring mechanism to move freely up and down.

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.

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.

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.

FAQ

Is this the same as the Thermo Panel 3e?

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 it lock?

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

Can an intruder remove it from the outside?

The thumbscrews are on the inside of the house so you cannot loosen them from the outside.

Does the flap lock?

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

Does this panel insulate well?

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

How do I measure for it?

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 it come in any color other than white?

No, but the vinyl 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 panel 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.

What do I do if my sliders meet in the middle?

You can install your panel in the middle and anchor one of your doors to it and leave the other one functional; essentially turning your two-door slider into one.

Not good. It was not made clear that it would only fit up to a certain height. My height needed is 80 inches. The door would only extend to 77&1/2 inches. I need to return it.

This doggie door is God sent miracle!

No longer have to get up in the middle of the night to let my dogs out or in the morning before I go to work. It may take a little while for your dogs to get the hang of using it, but eventually they will. Some reviews said the foam around the edges is less than adequate. I didn’t have the same opinion. It seemed plenty thick enough for shipping the door. Oh remember to unscrew the chrome knobs a little to release the extension part. I forgot about that lol.

Should of just bought a cheaper door

The quality of this door is terrible. For supporting an American made product I feel like I could have got the same quality from a Chinese made door. The screw holes in the extender piece below the door were in terrible shape when I received the door. It looked like a company with no quality control made the door. My sliding door measured 78.5” and the door didn’t even fit easily. I had to take the top adjustment piece off and jam foam weather seal tap into the top of the door. Also the foam weather seal they send you is junk! I ended up having to make another trip to Home Depot to buy $50 worth of quality rubber weather seal tape to finish the job correctly. You’d think for a “severe weather” friendly door they’d give you the best weather seal tape that also should have been white to match the white vinyl. Who ever made this door cut corners and gave me cheap material. I also should caulk around the extender bottoms piece below the door since I can see sunlight coming through it. Seriously disappointed in purchasing a premium American made dog door. Makes me sad how poorly made it was.

No longer have to get up in the middle of the night to let my dogs out or in the morning before I go to work. It may take a little while for your dogs to get the hang of using it, but eventually they will. Some reviews said the foam around the edges is less than adequate. I didn’t have the same opinion. It seemed plenty thick enough for shipping the door. Oh remember to unscrew the chrome knobs a little to release the extension part. I forgot about that lol.

Should of just bought a cheaper door

The quality of this door is terrible. For supporting an American made product I feel like I could have got the same quality from a Chinese made door. The screw holes in the extender piece below the door were in terrible shape when I received the door. It looked like a company with no quality control made the door. My sliding door measured 78.5” and the door didn’t even fit easily. I had to take the top adjustment piece off and jam foam weather seal tap into the top of the door. Also the foam weather seal they send you is junk! I ended up having to make another trip to Home Depot to buy $50 worth of quality rubber weather seal tape to finish the job correctly. You’d think for a “severe weather” friendly door they’d give you the best weather seal tape that also should have been white to match the white vinyl. Who ever made this door cut corners and gave me cheap material. I also should caulk around the extender bottoms piece below the door since I can see sunlight coming through it. Seriously disappointed in purchasing a premium American made dog door. Makes me sad how poorly made it was.
