Single flap or double flap? This is the single flap version. The single flap will be more than enough if you live in a more temperate climate. The flap would be on the inside of the wall on the same side as the locking cover. Double flaps will provide more insulation for your home, perfect for extreme climates. With a double-flap system, there is a flap on each side of the tunnel and dead air space in between to add extra insulation.  

Note: Endura Flap pet doors are not recommended for use by kittens or very small dogs. Cats have been successful using Small; however, a few have found the Medium difficult to use. We would not recommend using the Large or Extra Large or any of the double flap versions for cats.

Parts

  • 4 Corner Brackets
  • 24 Wood Screws
  • 1 Long Wood Screw
  • 1 Roll of Sealing Tunnel Tape
  • 1 Tube of Silicone
  • 1 Hole Transfer Jig with Level
  • 1 Locking Cover
  • 1 Cutout Template
  • 6 Plywood Tunnel Pieces (4 for XL)
  • 1 Inside Frame
  • 1 Outside Frame

Tools

  • Pencil
  • Hammer/Mallet
  • Measuring Tape
  • Electric Drill
  • Safety Gear
  • Stud Finder
  • Drywall Knife (or other for cutting inner wall)
  • Saw for Cutting Outer Wall (compatible with your wall material)
  • Razorblade (for trimming tape)
  • ⅜” Drill Bit
  • Philips Screwdriver

Step 1 Measure Your Pet

  • Measure your pet and make a mark at least 3” above your pet’s height on your wall, this will line up with the top of the template.
  • If a height taller than the max is needed, you will need to cut a new piece of lumber for your pet door tunnel.
  • Depending on pet height and the height of your baseboards you may need to cut into the baseboards to install the frame. If you want to avoid that, make sure to set the height accordingly.

Step 2 Prepare Wall for Installation

  • Find a section of your wall that is against a stud on one side, but does not contain any plumbing or wiring.
  • Once you find the stud, you can open a small area of the wall next to the stud that is large enough for you to feel around.
  • You can double-check for any plumbing, wiring, studs, or additional bracing that is in the way. Do not cut through plumbing, wiring, or bracing.
  • Extra-Large Size Only: This section will span from stud to stud for typical stud spacing of 16” on center (14.5" between studs).

Step 3 Make the Rough Cutout

Wall Mount Template Dimensions
Flap Size Width Height
Small 8" 14-5/8"
Medium 10" 18-5/8"
Large 12-1/8" 22-5/8"
Extra Large 14-3/8" 26-5/8"
  • Double check your template dimensions with the chart above before cutting into your wall.
  • Line up the provided template with the edge of the stud and tape it to the wall. Trace the side of the template along the stud. Remove the template, then cut along the stud line with a saw.
  • Line up the template again, adjusting to match the edge of the stud. Trace the remaining outline of the template. Remove the template and cut the rest of the lines drawn.
  • Remove insulation inside the wall as needed. You can save some to put back into open areas of the wall cavity.

Step 4 Measure the Studs

  • Determine the width of tunnel pieces to use by test fitting each width or measuring the width of studs inside the wall.
  • For 2x4 studs, use the narrower (3.5”) plywood sections.
  • For 2x6 studs, use the wider (5.5”) plywood sections.

Step 5 Insert the Vertical Tunnel Piece

  • Screw the long wood screw halfway into the middle of the vertical piece to act as a handle. Insert the vertical tunnel section inside the wall cavity and tap into place with a mallet or hammer. The face of the plywood should be flush with the cutout. Add back any insulation that can fit under the cutout.
  • Extra-Large Size Only: For standard 16" on center studs, the top and bottom pieces will span from stud to stud so you can skip this step.
  • Extra-Large Size Only: For non-standard stud spacing, you will need to get wood from a local hardware store to create the frame for the pet door. The frame opening should match the size of the provided template.

Step 6 Install Corner Brackets

  • Pre-install the four corner brackets at both ends of the two shorter plywood sections that match the width of your studs. The brackets must be flush with the edge of the short plywood pieces and centered.
  • Use only two screws per leg of the bracket.

Step 7 Install Bottom and Top Tunnel Pieces

  • Insert the bottom tunnel piece and screw it into the existing stud making sure it is even with the cut edge of the drywall and level or slightly angled down towards the outside. You may need a hammer/mallet to tap it into place if the fit is snug.
  • Screw the bottom tunnel piece to the vertical tunnel piece, making sure the vertical tunnel piece is resting on the bottom of the inner wall for support.
  • Use the long wood screw partially inserted into the vertical piece to hold onto it.
  • Insert the top tunnel piece and screw it into the existing stud and vertical tunnel piece making sure it’s level and even with the cut edge of the drywall.

Step 8 Drill Through the Outer Wall

  • Remove the long screw from the vertical tunnel piece.
  • Using the provided transfer jig, drill ⅜” holes through the outer wall from the inside of the opening on the top-left and bottom-right corners.
  • Make sure you use the appropriate type of drill for your outer wall.

Step 9 Mark Where to Cut the Outer Wall

  • From the outside, line up the hole transfer jig with the drilled holes. Level the hole transfer jig and mark the jig’s corners on your wall.
  • Use the drill bit as a pin to help line up the hole transfer jig with the hole.
  • Using the template lined up with marked corners, mark all cut lines.

Step 10 Cut Outer Wall Opening

  • Cut along the inside of the lines as accurately as possible.
  • Be careful not to damage the corner brackets and screws near the corners.
  • Trim up any areas that aren’t flush with the plywood tunnel. Clean the inside of your wall of any dust or debris.

Step 11a Prepare Tunnel for Sealing Tunnel Tape

  • Make sure the tunnel area is clean and dry.
  • The edge of the sealing tape should line up with your inside wall, with the rest of the tape overhanging the tunnel on the outside.
  • To apply the sealing tunnel tape, start at the middle of the upper tunnel and apply the tape all around the tunnel, ending with a slight overlap at the top. Make sure to press the tape tightly into the corners as you go.
  • Once in place, firmly apply pressure all along the tape to activate the adhesive.

Step 11b Apply Sealing Tunnel Tape

  • Cut each corner up to the outer wall.
  • Fold back each piece of the sealing tape against the outer wall, pressing firmly.
  • Apply caulking to the openings in all four corners, sealing the cut area of the tape to the outer wall.
  • The sealing tape will be trimmed in a future step.

Step 12 Screw in the Frames

  • Make sure the four tabs are upright and snug to the inside frame. You may have to loosen the screw to rotate it into place using a Phillips screwdriver.
  • Insert the inside frame and level it in the opening with the hole transfer jig. While holding the frame flush against the wall, use four wood screws to screw the mounting tabs to the inside of the tunnel.
  • If there are larger gaps you can pre-bend the mounting tab toward the tunnel.

Step 13 Install the Outside Frame

  • Repeat installation step #12 for the outside frame, making sure the flap(s) swing through both frames without interference.

Step 14 Seal the Inside Frame

  • From the outside, apply silicone in the tunnel, around the sides and bottom edges of the inside frame. This will seal the tunnel tape to prevent water intrusion.

Step 15 Seal the Outside Frame

  • Use a sharp razor blade to trim off any excess tunnel tape that is sticking out past the outside frame on all four sides.
  • Apply silicone where the outside frame meets the exterior wall on the top and sides, but leave the bottom open to allow for drainage.

FAQ

Can a large dog and a cat use the same double flap door flaps?

We recommend cats use the small flap size since the larger flaps might be difficult for them to push through. However, if you have cats and dogs sharing a door, you can decrease the magnetic resistance of the threshold on large and extra-large sizes making it easier for a cat to use. For small or medium pet doors you can offset the magnets slightly which can also decrease the magnetic strength.

Can I install this into my sliding glass door or screen door?

Unfortunately, wall kit pet doors cannot be installed into screen or sliding glass patio doors. However, you can get the Thermo Panel 3e pet door insert, which will fit into the track of your sliding door.

How easy is the door installation process?

It's a simple DIY process, but it can be difficult for people who are not already handy. You should consider hiring professional help in order to make sure you don't ruin your interior or exterior walls.

How do I know what flap size will fit my dog?

When installing the Endura Flap extreme weather dog door wall mount you want it to clear the top of your dog's back by at least 1". You also want the step over to be comfortable, no more than 1/3 your pet's shoulder height. Lastly, you want the width to allow your pet to go through without touching the sides, so about 1" wider than them.

Will this work for walls thicker than 7 3/4"?

For walls thicker than 7 ¾" check out the Endura Pet Door for Thick Walls in Single and Double Flap.

Is the flap flexible? Seems like it would trap a dog if it backed up.

The Endura Flap is slightly more rigid than other economy-style flaps, but it is a safe, soft, flexible flap.

Is the flap loud when the dog goes in or out?

When the flap gets to its resting place there is a snapping sound when the magnets employ. This sound lets you know the door is doing its job sealing out the elements and keeping your heated or cooled air inside.

What side does the locking cover slide in?

All locking covers slide in from the top. If you purchase a double flap model, the locking cover can be used on the inside or outside the frame. If you purchase a single flap, the locking cover is on the interior frame (the side closest to the inside of your home).

Are replacement flaps available?

Yes, we carry Endura Replacement Flaps. They will work for all Endura models (wall mount, doggy door mount, kennel doors, window sashes, and sliding glass door patio pet doors).

I have a dog that I want to let out, but I want to prevent our cats from using it. Can the door be weighted to keep them from using it?

You can increase the magnetic strength of the door by purchasing additional magnets here. Some people have found success doing this and keeping their cats inside.

What material is the tunnel made

It is made of wood and protected by a sturdy sealing tape.How can I make the Endura Flap more aesthetically pleasing?The Endura Flap Designer Series features a less prominent frame so that you can install your home's trimming around it. The Endura Flap Builder series is the same door,but made for DIY enthusiasts who want to build out their wall on their own. Can I install this pet door into a glass surface?The Wall Mount is not ideal for in-glass installations.

FINALLY!

We have been through so many of the "pet store variety" dog doors, in hindsight, they all would have paid for one of these VERY nice dog doors. Don't let the price of this dog door scare you - it will pay for itself in replacement flaps on the cheaper doors, and more importantly, those cheaper dog doors kept changing sizes on me! We had to go UP in size and cut the door again - and anyone who's done that knows it's not easy. So we decided to spend the money and haven't been more satisfied with a dog product! Live in MT where it gets very cold and notice a huge difference in heat retention, we usually have between 3-5 dogs and they barrel through the door all day long and it's held up perfectly. Great Door, Great Design, Great Company.

Superb as always

We've been using Endura Flaps for at least 20 years. We had excellent performance from a large sized double flap door for 25 years without having to change anything in the original installation. During that time we always had at least two dogs, either greyhounds or salukis who banged in and out countless times often with considerable enthusiasm. The double flap was absolutely protective against all weathers, including on those rare occasions when we had unusual freezes with outside temps in the single digits (we live in Bellingham, WA). When the last of our large animals passed on, we went over to MiniSchnauzers but only last year did we change our original installation, opting for the single flap to facilitate ease of in and out for an 18 pound canine instead of our 40 pound former athletes. The new single flap works perfectly and, given its construction, will surely be as weather insulating as the former set. Brilliant technology! Complete satisfaction in every respect.

The best dog door in the world!

I purchased my first Endura Flap Dog Door in 2008. It has been used for over the years by several dogs, a 90 lb black lab and two basset hounds. It keeps out all bad weather and is easy for the dogs to use. I’m in the process of installing new decks and decided that it was time to treat myself and my present 65 lb basset hound to a beautfiul new Endura Dog Door.

2 new doors

We have had these doors in our home for 15 years and I only had to replace the flaps once. Our home burned down last August and has been rebuilt so the only choice was to put in new dura flaps. Our summer temps in Yuma AZ teach out To 120+ so we have a dual flap on the outside wall and a single works fine on the interior wall of the workshop to the house to keep everything comfy inside.

Step 4 Measure the Studs

  • Determine the width of tunnel pieces to use by test fitting each width or measuring the width of studs inside the wall.
  • For 2x4 studs, use the narrower (3.5”) plywood sections.
  • For 2x6 studs, use the wider (5.5”) plywood sections.

Step 5 Insert the Vertical Tunnel Piece

  • Screw the long wood screw halfway into the middle of the vertical piece to act as a handle. Insert the vertical tunnel section inside the wall cavity and tap into place with a mallet or hammer. The face of the plywood should be flush with the cutout. Add back any insulation that can fit under the cutout.
  • Extra-Large Size Only: For standard 16" on center studs, the top and bottom pieces will span from stud to stud so you can skip this step.
  • Extra-Large Size Only: For non-standard stud spacing, you will need to get wood from a local hardware store to create the frame for the pet door. The frame opening should match the size of the provided template.

Step 6 Install Corner Brackets

  • Pre-install the four corner brackets at both ends of the two shorter plywood sections that match the width of your studs. The brackets must be flush with the edge of the short plywood pieces and centered.
  • Use only two screws per leg of the bracket.

Step 7 Install Bottom and Top Tunnel Pieces

  • Insert the bottom tunnel piece and screw it into the existing stud making sure it is even with the cut edge of the drywall and level or slightly angled down towards the outside. You may need a hammer/mallet to tap it into place if the fit is snug.
  • Screw the bottom tunnel piece to the vertical tunnel piece, making sure the vertical tunnel piece is resting on the bottom of the inner wall for support.
  • Use the long wood screw partially inserted into the vertical piece to hold onto it.
  • Insert the top tunnel piece and screw it into the existing stud and vertical tunnel piece making sure it’s level and even with the cut edge of the drywall.

Step 8 Drill Through the Outer Wall

  • Remove the long screw from the vertical tunnel piece.
  • Using the provided transfer jig, drill ⅜” holes through the outer wall from the inside of the opening on the top-left and bottom-right corners.
  • Make sure you use the appropriate type of drill for your outer wall.

Step 9 Mark Where to Cut the Outer Wall

  • From the outside, line up the hole transfer jig with the drilled holes. Level the hole transfer jig and mark the jig’s corners on your wall.
  • Use the drill bit as a pin to help line up the hole transfer jig with the hole.
  • Using the template lined up with marked corners, mark all cut lines.

Step 10 Cut Outer Wall Opening

  • Cut along the inside of the lines as accurately as possible.
  • Be careful not to damage the corner brackets and screws near the corners.
  • Trim up any areas that aren’t flush with the plywood tunnel. Clean the inside of your wall of any dust or debris.

Step 11a Prepare Tunnel for Sealing Tunnel Tape

  • Make sure the tunnel area is clean and dry.
  • The edge of the sealing tape should line up with your inside wall, with the rest of the tape overhanging the tunnel on the outside.
  • To apply the sealing tunnel tape, start at the middle of the upper tunnel and apply the tape all around the tunnel, ending with a slight overlap at the top. Make sure to press the tape tightly into the corners as you go.
  • Once in place, firmly apply pressure all along the tape to activate the adhesive.

Step 11b Apply Sealing Tunnel Tape

  • Cut each corner up to the outer wall.
  • Fold back each piece of the sealing tape against the outer wall, pressing firmly.
  • Apply caulking to the openings in all four corners, sealing the cut area of the tape to the outer wall.
  • The sealing tape will be trimmed in a future step.

Step 12 Screw in the Frames

  • Make sure the four tabs are upright and snug to the inside frame. You may have to loosen the screw to rotate it into place using a Phillips screwdriver.
  • Insert the inside frame and level it in the opening with the hole transfer jig. While holding the frame flush against the wall, use four wood screws to screw the mounting tabs to the inside of the tunnel.
  • If there are larger gaps you can pre-bend the mounting tab toward the tunnel.

Step 13 Install the Outside Frame

  • Repeat installation step #12 for the outside frame, making sure the flap(s) swing through both frames without interference.

Step 14 Seal the Inside Frame

  • From the outside, apply silicone in the tunnel, around the sides and bottom edges of the inside frame. This will seal the tunnel tape to prevent water intrusion.

Step 15 Seal the Outside Frame

  • Use a sharp razor blade to trim off any excess tunnel tape that is sticking out past the outside frame on all four sides.
  • Apply silicone where the outside frame meets the exterior wall on the top and sides, but leave the bottom open to allow for drainage.

FAQ

Can a large dog and a cat use the same double flap door flaps?

We recommend cats use the small flap size since the larger flaps might be difficult for them to push through. However, if you have cats and dogs sharing a door, you can decrease the magnetic resistance of the threshold on large and extra-large sizes making it easier for a cat to use. For small or medium pet doors you can offset the magnets slightly which can also decrease the magnetic strength.

Can I install this into my sliding glass door or screen door?

Unfortunately, wall kit pet doors cannot be installed into screen or sliding glass patio doors. However, you can get the Thermo Panel 3e pet door insert, which will fit into the track of your sliding door.

How easy is the door installation process?

It's a simple DIY process, but it can be difficult for people who are not already handy. You should consider hiring professional help in order to make sure you don't ruin your interior or exterior walls.

How do I know what flap size will fit my dog?

When installing the Endura Flap extreme weather dog door wall mount you want it to clear the top of your dog's back by at least 1". You also want the step over to be comfortable, no more than 1/3 your pet's shoulder height. Lastly, you want the width to allow your pet to go through without touching the sides, so about 1" wider than them.

Will this work for walls thicker than 7 3/4"?

For walls thicker than 7 ¾" check out the Endura Pet Door for Thick Walls in Single and Double Flap.

Is the flap flexible? Seems like it would trap a dog if it backed up.

The Endura Flap is slightly more rigid than other economy-style flaps, but it is a safe, soft, flexible flap.

Is the flap loud when the dog goes in or out?

When the flap gets to its resting place there is a snapping sound when the magnets employ. This sound lets you know the door is doing its job sealing out the elements and keeping your heated or cooled air inside.

What side does the locking cover slide in?

All locking covers slide in from the top. If you purchase a double flap model, the locking cover can be used on the inside or outside the frame. If you purchase a single flap, the locking cover is on the interior frame (the side closest to the inside of your home).

Are replacement flaps available?

Yes, we carry Endura Replacement Flaps. They will work for all Endura models (wall mount, doggy door mount, kennel doors, window sashes, and sliding glass door patio pet doors).

I have a dog that I want to let out, but I want to prevent our cats from using it. Can the door be weighted to keep them from using it?

You can increase the magnetic strength of the door by purchasing additional magnets here. Some people have found success doing this and keeping their cats inside.

What material is the tunnel made

It is made of wood and protected by a sturdy sealing tape.How can I make the Endura Flap more aesthetically pleasing?The Endura Flap Designer Series features a less prominent frame so that you can install your home's trimming around it. The Endura Flap Builder series is the same door,but made for DIY enthusiasts who want to build out their wall on their own. Can I install this pet door into a glass surface?The Wall Mount is not ideal for in-glass installations.

FINALLY!

We have been through so many of the "pet store variety" dog doors, in hindsight, they all would have paid for one of these VERY nice dog doors. Don't let the price of this dog door scare you - it will pay for itself in replacement flaps on the cheaper doors, and more importantly, those cheaper dog doors kept changing sizes on me! We had to go UP in size and cut the door again - and anyone who's done that knows it's not easy. So we decided to spend the money and haven't been more satisfied with a dog product! Live in MT where it gets very cold and notice a huge difference in heat retention, we usually have between 3-5 dogs and they barrel through the door all day long and it's held up perfectly. Great Door, Great Design, Great Company.

Superb as always

We've been using Endura Flaps for at least 20 years. We had excellent performance from a large sized double flap door for 25 years without having to change anything in the original installation. During that time we always had at least two dogs, either greyhounds or salukis who banged in and out countless times often with considerable enthusiasm. The double flap was absolutely protective against all weathers, including on those rare occasions when we had unusual freezes with outside temps in the single digits (we live in Bellingham, WA). When the last of our large animals passed on, we went over to MiniSchnauzers but only last year did we change our original installation, opting for the single flap to facilitate ease of in and out for an 18 pound canine instead of our 40 pound former athletes. The new single flap works perfectly and, given its construction, will surely be as weather insulating as the former set. Brilliant technology! Complete satisfaction in every respect.

The best dog door in the world!

I purchased my first Endura Flap Dog Door in 2008. It has been used for over the years by several dogs, a 90 lb black lab and two basset hounds. It keeps out all bad weather and is easy for the dogs to use. I’m in the process of installing new decks and decided that it was time to treat myself and my present 65 lb basset hound to a beautfiul new Endura Dog Door.

2 new doors

We have had these doors in our home for 15 years and I only had to replace the flaps once. Our home burned down last August and has been rebuilt so the only choice was to put in new dura flaps. Our summer temps in Yuma AZ teach out To 120+ so we have a dual flap on the outside wall and a single works fine on the interior wall of the workshop to the house to keep everything comfy inside.
