Single flap or double flap? This is the double flap version. The double flap 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.

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 cutout.
  • 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 location clear of plumbing, electrical and other obstructions. If you have stud construction choose a spot against one stud when possible.
  • Use the included cutout template to mark out the rough opening in the wall. Make sure your lines are level. This cut out will leave space for the included tunnel material.
  • Double check your template dimensions with the chart before cutting into your wall.

Step 3 Make the Rough Cutout

  • Cut through your wall with the appropriate tools.
  • In some cases, you may have to cut and brace a stud. See local building codes to ensure this is done properly. We recommend hiring a professional if you are unsure what to do.
  • Remove insulation inside the wall as needed. You can save some to put back into open areas of the wall cavity.

Step 4 Add a Bottom Support Stud

  • The step won't be necessary for most cinder block walls.
  • Add a bottom support stud between the studs in your wall.
  • Add any other supports or bracing as needed.

Step 5 Create A Tunnel Liner Box

  • Create a tunnel liner box using 1/2" plywood.
  • The depth should be 1/8" less than the thickness of the wall.

Step 6 Draw Cut Line On Tunnel

insert pet door into wall
insert pet door into wall
  • Slide tunnel box into opening until the inside of the box is flush or slightly inside the surface of your inner wall. Mark a line all around the box at the outer wall. Remove the box from the wall.
  • Relocate the tunnel box screws so they are all within the usable area of the tunnel. Cut off the excess tunnel material line.
  • Cut just inside your line to make sure the tunnel does not end up sticking out of the wall after installation. It should be flush or just inside the wall surface on both inside and outside.

Step 7 Attach the Tunnel Liner Box

  • Insert the tunnel liner box into the rough cutout opening. Use the provided shims to get the tunnel level and square.
  • Use the provided long wood screws and/or concrete screws to attach the tunnel box to a nearby stud, brick, concrete, or bottom support.
  • Trim off shims flush to the wall. You can score with a knife then snap them off.
  • If you are installing your tunnel into or against concrete, you may need a moisture barrier. Check your local building codes for more information.

Step 8 Apply Spray Foam Sealant

  • Use the spray foam sealant to fill any gaps around the tunnel box.
  • Once the sealant dries, trim off any excess.

Step 9a Prepare Tunnel for Sealing Tunnel Tape

  • Make sure that the spray foam sealant is dry and that the tunnel area is clean.
  • The edge of the sealing tape should line up with your inside wall. For deep walls, you will need to use multiple layers of tunnel tape, overlapping 1" on each piece to cover the entire tunnel. Make sure to have at least 1" of tape overhand the outside wall.
  • 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 9b 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 10 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. 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 11 Install the Outside Frame

  • Repeat installation step #10 for the outside frame, making sure the flap(s) swing through both frames without interference.

Step 12 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 to prevent water intrusion.

Step 13 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.

Step 14 Add Home Trim

  • Add trim to the interior frame to suit your home design.
  • Use caulking and paint as desired

  • If needed, use spray foam sealant to fill any gaps around the tunnel box.
  • Once the sealant dries, trim off any excess.

Step 8 Seal the Tunnel

  • Use an outdoor rated paint to seal any exposed wood in the tunnel.

Step 9 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. While holding the frame flush against the wall, use four wood screws to screw the mounting tabs to the inside of the tunnel.

FAQ

Can a large dog and a cat use the same double flap Endura Flap Dog Doors for Walls?

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 Endura Flap wall mount pet 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.

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

When installing the Endura Flap wall mount doggie door 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 7-3/4", check out the Endura Flap Pet Door for Deep Walls (also available in single 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 in wall pet door replacement flaps available?

Yes, we carry Endura Pet Door Replacement Flaps. They will work for all Endura Flap Pet Door 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 flap on the Endura wall mount pet door be weighted to keep them from using it?

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

What material is the Endura Dog Door for Walls’ tunnel made from?

It is made of wood and sealing tape.

What is the difference between this door and the Endura Flap Builder Series?

The Endura Flap Builder Series has the same frame, but does not come with any additional supplies needed to install your pet door.

Absolutely Worth the Money

I purchased this door two years ago and it still works great. We have 2 dogs that use it probably 30-40 times a day. It keeps out the cold even when it is 10 below zero here in upstate NY. It is so nice not having to rush home to let the dogs out. We have even left them home overnight without worrying (with an auto food and water dispenser).

  • Slide tunnel box into opening until the inside of the box is flush or slightly inside the surface of your inner wall. Mark a line all around the box at the outer wall. Remove the box from the wall.
  • Relocate the tunnel box screws so they are all within the usable area of the tunnel. Cut off the excess tunnel material line.
  • Cut just inside your line to make sure the tunnel does not end up sticking out of the wall after installation. It should be flush or just inside the wall surface on both inside and outside.

Step 7 Attach the Tunnel Liner Box

  • Insert the tunnel liner box into the rough cutout opening. Use the provided shims to get the tunnel level and square.
  • Use the provided long wood screws and/or concrete screws to attach the tunnel box to a nearby stud, brick, concrete, or bottom support.
  • Trim off shims flush to the wall. You can score with a knife then snap them off.
  • If you are installing your tunnel into or against concrete, you may need a moisture barrier. Check your local building codes for more information.

Step 8 Apply Spray Foam Sealant

  • Use the spray foam sealant to fill any gaps around the tunnel box.
  • Once the sealant dries, trim off any excess.

Step 9a Prepare Tunnel for Sealing Tunnel Tape

  • Make sure that the spray foam sealant is dry and that the tunnel area is clean.
  • The edge of the sealing tape should line up with your inside wall. For deep walls, you will need to use multiple layers of tunnel tape, overlapping 1" on each piece to cover the entire tunnel. Make sure to have at least 1" of tape overhand the outside wall.
  • 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 9b 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 10 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. 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 11 Install the Outside Frame

  • Repeat installation step #10 for the outside frame, making sure the flap(s) swing through both frames without interference.

Step 12 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 to prevent water intrusion.

Step 13 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.

Step 14 Add Home Trim

  • Add trim to the interior frame to suit your home design.
  • Use caulking and paint as desired

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 cutout.
  • 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 location clear of plumbing, electrical and other obstructions. If you have stud construction choose a spot against one stud when possible.
  • Use the included cutout template to mark out the rough opening in the wall. Make sure your lines are level. This cut out will leave space for the tunnel material.
  • Double check your template dimensions with the chart before cutting into your wall.

Step 3 Make the Rough Cutout

  • Cut through your wall with the appropriate tools.
  • In some cases, you may have to cut and brace a stud. See local building codes to ensure this is done properly. We recommend hiring a professional if you are unsure what to do.
  • Remove insulation inside the wall as needed. You can save some to put back into open areas of the wall cavity.

Step 4 Add a Bottom Support Stud

  • The step won't be necessary for most cinder block walls.
  • Add a bottom support stud between the studs in your wall.
  • Add any other supports or bracing as needed.

Step 5 Create A Tunnel Liner Box

  • Create a tunnel liner box using 1/2" plywood.
  • The depth should be 1/8" less than the thickness of the wall.

Step 6 Attach the Tunnel Liner Box

  • Insert the tunnel liner box into the rough cutout opening. Use shims to get the tunnel level and square.
  • Use wood screws and/or concrete screws to attach the tunnel box to a nearby stud, brick, concrete, or bottom support.
  • Trim off shims flush to the wall. You can score with a knife then snap them off.

Step 7 Apply Spray Foam Sealant

  • If needed, use spray foam sealant to fill any gaps around the tunnel box.
  • Once the sealant dries, trim off any excess.

Step 8 Seal the Tunnel

  • Use an outdoor rated paint to seal any exposed wood in the tunnel.

Step 9 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. 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 10 Install the Outside Frame

  • Repeat installation step #10 for the outside frame, making sure the flap(s) swing through both frames without interference.

Step 11 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 to prevent water intrusion.

Step 12 Seal the Outside Frame

  • Apply silicone where the outside frame meets the exterior wall on the top and sides, but leave the bottom open to allow for drainage.

Step 13 Add Home Trim

FAQ

Can a large dog and a cat use the same double flap Endura Flap Dog Doors for Walls?

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 Endura Flap wall mount pet 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.

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

When installing the Endura Flap wall mount doggie door 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 7-3/4", check out the Endura Flap Pet Door for Deep Walls (also available in single 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 in wall pet door replacement flaps available?

Yes, we carry Endura Pet Door Replacement Flaps. They will work for all Endura Flap Pet Door 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 flap on the Endura wall mount pet door be weighted to keep them from using it?

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

What material is the Endura Dog Door for Walls’ tunnel made from?

It is made of wood and sealing tape.

What is the difference between this door and the Endura Flap Builder Series?

The Endura Flap Builder Series has the same frame, but does not come with any additional supplies needed to install your pet door.

Absolutely Worth the Money

I purchased this door two years ago and it still works great. We have 2 dogs that use it probably 30-40 times a day. It keeps out the cold even when it is 10 below zero here in upstate NY. It is so nice not having to rush home to let the dogs out. We have even left them home overnight without worrying (with an auto food and water dispenser).
