Single Flap Wall Mount

Step 1 Measure your Pet

  • If you have not yet measured your pet, watch this video to ensure the pet door will work.
  • Tape the provided template onto the wall in the desired location. Use a level to straighten the edges of the template.
  • The top edge of the cutout should be at least 3.2 cm above the tallest point of your pet’s back
  • Triple check for studs in the bottom, middle, and top of where the cut out would be after hanging the template on each edge including the bottom. Check for baseboard height, we suggest the step-over be around 7cm - 10cm when going through walls, so it may be necessary to trim

Step 2 Check Wall For Wires/Pipes

  • Mark the centers of the four holes using a pencil or nail. Remove the template
  • Drill a small hole in the middle to peek into the wall to check for wires/pipes. If you’re clear, move on to the next step to drill through the marked holes.
  • Professional help is recommended if you are unfamiliar with these processes
  • Before cutting the entire opening make a small square test hole right at the bottom part of the cutout, roughly 15cm by 15cm. Use this test hole to take a peek at the interior of the wall to make sure that there isn't any wiring, plumbing, etc. This way if you do find obstructions all you have to do is make a small patch to the wall.

Step 3 Drill Holes & Rough Cutout

  • Drill the marked 9,5 mm) holes through the interior and exterior walls
  • If the drill bit will not go all the way through the wall, you will need to drill through each side separately. (See how here…)
  • Use a level to make sure your lines will be straight. It is a good idea to remeasure your outline to ensure dimensions are accurate
  • Now, cut the opening out along the lines
  • You can drill through both the interior and exterior wall, but you need a drill that is at least 15cm - 30cm long. This can be difficult to keep straight and level and having a professional is recommended. A drill with a built-in level would help. An alternative cut method where you cut the inside and outside walls separately is available.

Step 4 Check Weather-Stripping

  • Ensure the weather-stripping is firmly pressed in the groove on both frames.
  • When installing the weatherstripping make sure not to stretch it out, because it compresses over time and you want it to keep the wiggle room.

Step 5 Assemble Tunnel

  • Assemble the tunnel onto the interior frame (frame that holds locking cover), without bending tabs, to understand how they will fit together
  • Trim the four sheet metal tunnel pieces so that they are 0.6 cm shorter than the thickness of the wall. We recommend using a jigsaw, but you could use other metal cutting tools instead
  • Be careful to trim the correct side. Do not trim the side of the short tunnel pieces that attach to the top and bottom of the flap frame. Also, do not trim the side of the long tunnel pieces with three small holes in them that attach to the sides of the flap frame.
  • To reduce vibration, the pieces should be firmly clamped to a piece of wood
  • Cut the tunnels one at a time, by clamping them down tightly to a board to avoid vibration. Use a wooden block to guide the jigsaw for a straighter cut.

Step 6 Bend Tunnel Tabs

  • Bend the frame attachment tabs on the two smaller tunnel pieces 90 degrees upward along the perforations
  • Be careful to bend the tabs in the right direction. The tabs will break if bent more than once. Bend these tabs as shown with the arrow. Tunnel pieces can be bent once in either direction before breaking.

Step 7 Attach Small Tunnel Pieces

  • Remove the two screws at the top and two screws at the bottom of the Interior Flap Frame. If you removed the cover already, the OUTSIDE frame screw holes have threaded nuts in them and you can see them shine.
  • Attach the smaller tunnel pieces to the top and bottom of the Interior Flap Frame using the two screws

Step 8 Attach Larger Tunnel Pieces

  • Slide the larger tunnel pieces onto the finger tabs on the small top and bottom tunnel pieces. Bend the finger tabs down as shown
  • The handle of a screwdriver works well for bending the tabs

Step 9 Apply Silicone to Tunnel

  • Apply a bead of the provided silicone sealant along the inside of the tunnel where it mates with the interior frame, and along the tunnel seams

Step 10 Position Interior Frame & Tunnel

  • Place the Interior Frame, with the tunnel attached, into the opening in the wall from the inside of the building. Place the Exterior Frame into the tunnel.
  • A partner can help you hold the Exterior Frame
  • For really large dogs you may wish to support the bottom of the tunnel with a piece of wood

Step 11 Attach Exterior Frame

  • Insert the threaded rods with the barrel nuts into the four holes in the Interior Frame (the frame that has a locking cover), and screw the threaded rods into the Exterior Frame finger tight
  • Check that the pet door is level and tighten the threaded rods until the weather stripping compresses fully
  • Be careful not to overtighten
  • If you do not have a partner to help guide the rods through the opening to the other frame, you can put your hand through the door and hold a mirror or smartphone facing the hole on the outside to help you see.

Step 12 Remove Excess Threaded Rod

  • With the pet door leveled and all four threaded rods tightened, wiggle the end of the threaded rods that are protruding out of the exterior frame until the ends snap off
  • If the rods are not long enough to grip, you can use a pair of pliers to bend the rods until they snap off

Step 13 Seal with Silicone

  • Apply a bead of silicone sealant along the inside of the tunnel where it mates with the exterior frame
  • In addition to sealing inside the tunnel of the pet door we recommend that you also seal the outside frame around the pet door
  • This is especially important on the exterior frame to prevent any water from leaking into the wall and causing damage

Step 14 Insert Hole Plugs

  • Tap the hole plugs into the Interior and Exterior Frames
  • You can use a rubber mallet, wood block and hammer, or a similar non-metal tool

Special Wall Situations

If your wall is over 20,3 cm thickness,the included tunnel will not be long enough. Your contractor can install the pet door in thicker walls by fabricating a custom tunnel. This can be done by using plywood, sheet metal, brick, or stone to line the cut out. One frame would be attached to the inside of the house and one frame to the outside. The provided template + instructions might not be accurate in a custom installation. Different hardware* will be required depending on what you are using for the tunnel and how you are mounting the frames to the wall. In all cases it is extremely important to make sure that the tunnel is sealed with silicone or caulking to prevent any damage from water leaking into the wall.

Wall Siding: You can choose to place the pet door on top of the siding. If you choose this option then you will need to make sure to take care of completely caulking and sealing any gaps that you have to prevent water damage to the wall.

You can also recess the pet door frame into the siding. In this case you would make the recommended rough opening according to the template. Then on the exterior you would cut away the siding only to frame the outside dimension of the pet door. Also be sure to properly caulk and seal around the frame. Some people choose to build a frame to surround the pet door, if you do this, you’ll have to take the same precautions with sealing the wall to prevent water damage.

Alternative Rough Cut Method

This method can be easier in some cases than trying to go through both walls with one pass.

  • Step 1: Drill through the interior wall and draw lines connecting the outside part of the holes.
  • Step 2: Use a hand saw or reciprocating saw to cut out the inside sheet rock along the drawn line.
  • Step 3: Remove any insulation to expose the back of the exterior wall. Measuring very carefully and making sure all is level drill holes from the inside of exterior wall to the outside.
  • Step 4: Tape off the inside opening with a trash bag. This will prevent the dust and debris from going all over and makes clean up much easier.
  • Step 5: Make a mark from the inner side of the drilled holes on the exterior wall. It is a good idea to measure and level your outline from the outside, to ensure your hole will be the correct size.
  • Step 6: Use the pilot holes and a circular saw (use a concrete blade if you have concrete or stucco exterior) to cut out the exterior. Place a piece of cardboard under the saw to prevent it from damaging the exterior.
  • Step 7: Finish the opening with a reciprocating saw and if possible have a spotter inside.

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 2.5cm. 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 2.5cm wider than them.

Will this work for walls thicker than 20.32cm?

For walls thicker than 20.32cm, you can build your own tunnel out of wood or sheet metal.

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 durable aluminum.

Best Dog Door Hands Down

I bought this door in 2016 for my dog who needed outdoor access while I was working 10 to 12 hour shifts. It's lasted remarkably in our hot/cold area. Did have one issue with the exterior flap coming apart at one seam, so I called customer service, explained the issue, and had a set of replacement flaps at my doorstep within a week, free of charge. All around amazing company and products.

Very durable

We have the double flap wall mount. It has held up very well to our 3 german shepards of which go in and out it a LOT. This is expensive but you don't have to worry about it. The only maintenance I've done is clean in between the flaps in the wall which by design will collect hair and dirt. Not a big deal. We've had it for about 6 years now.

Medium wall dog door

This was an insane 5 hour project. Following the directions to a T. The long screw heads stripped WAY too easy, trying to get one out to try to get a straighter hole, it snapped. So then trying to figure out a way to rig up some sort of solution. Got some washers and nuts, but now the decorative buttons are useless to try to make it look better. The directions of cutting the tunnel 1/4” shorter than the wall, left an almost 3/4” gap and now we have to figure out a way to build up the tunnel and make it weather proof/air tight. The directions need to specify to install it against the house outside, not on the siding. There is no way to snug it secure over the siding, especially with the tunnel too short and the long screws breaking. A bit disappointed with paying over $500 for a dog door and having to ‘make do’ and rig up alternate ways to install it to make it work. Now just to train the dogs to actually use it. Living in Wisconsin, I hope that I don’t regret even more, spending this amount of money, and it will be worth it. Questioning that decision tonight! Sharon Wagner

Great Dog Door

We bought the Endura double flap dog door to replace a non-premium dog door I had installed in the wall several years ago. The old dog door began to break soon after it was installed, and it had large gaps that let air flow freely through the dog door. The new Endura dog door was easy to install. It required a slightly larger wall opening than the prior door, but after a few cuts in the wall, the new Endura dog door slid in, as did the bolts that run from the inside flap to the outside flap. Although we live in a relatively mild climate, we installed a double flap model. The old dog door had two flaps, and I didn’t want the outside of the new dog door to be flapless (with only an inside flap). The magnets for the Endura dog door are much stronger than those on our old dog door, so it took our three small dogs about a week to get used to it. (I think the dogs initially thought the dog door was closed because the Endura flaps do not swing freely like the flaps did on our old dog door.) I am very happy with our new Endura dog door, and I’m glad that I didn’t replace our old dog door with another inferior dog door that would break shortly after being installed. I can tell that this new Endura dog door will last a very long time.

  • Slide the larger tunnel pieces onto the finger tabs on the small top and bottom tunnel pieces. Bend the finger tabs down as shown
  • The handle of a screwdriver works well for bending the tabs

Step 9 Apply Silicone to Tunnel

  • Apply a bead of the provided silicone sealant along the inside of the tunnel where it mates with the interior frame, and along the tunnel seams

Step 10 Position Interior Frame & Tunnel

  • Place the Interior Frame, with the tunnel attached, into the opening in the wall from the inside of the building. Place the Exterior Frame into the tunnel.
  • A partner can help you hold the Exterior Frame
  • For really large dogs you may wish to support the bottom of the tunnel with a piece of wood

Step 11 Attach Exterior Frame

  • Insert the threaded rods with the barrel nuts into the four holes in the Interior Frame (the frame that has a locking cover), and screw the threaded rods into the Exterior Frame finger tight
  • Check that the pet door is level and tighten the threaded rods until the weather stripping compresses fully
  • Be careful not to overtighten
  • If you do not have a partner to help guide the rods through the opening to the other frame, you can put your hand through the door and hold a mirror or smartphone facing the hole on the outside to help you see.

Step 12 Remove Excess Threaded Rod

  • With the pet door leveled and all four threaded rods tightened, wiggle the end of the threaded rods that are protruding out of the exterior frame until the ends snap off
  • If the rods are not long enough to grip, you can use a pair of pliers to bend the rods until they snap off

Step 13 Seal with Silicone

  • Apply a bead of silicone sealant along the inside of the tunnel where it mates with the exterior frame
  • In addition to sealing inside the tunnel of the pet door we recommend that you also seal the outside frame around the pet door
  • This is especially important on the exterior frame to prevent any water from leaking into the wall and causing damage

Step 14 Insert Hole Plugs

  • Tap the hole plugs into the Interior and Exterior Frames
  • You can use a rubber mallet, wood block and hammer, or a similar non-metal tool

Special Wall Situations

If your wall is over 20,3 cm thickness,the included tunnel will not be long enough. Your contractor can install the pet door in thicker walls by fabricating a custom tunnel. This can be done by using plywood, sheet metal, brick, or stone to line the cut out. One frame would be attached to the inside of the house and one frame to the outside. The provided template + instructions might not be accurate in a custom installation. Different hardware* will be required depending on what you are using for the tunnel and how you are mounting the frames to the wall. In all cases it is extremely important to make sure that the tunnel is sealed with silicone or caulking to prevent any damage from water leaking into the wall.

Wall Siding: You can choose to place the pet door on top of the siding. If you choose this option then you will need to make sure to take care of completely caulking and sealing any gaps that you have to prevent water damage to the wall.

You can also recess the pet door frame into the siding. In this case you would make the recommended rough opening according to the template. Then on the exterior you would cut away the siding only to frame the outside dimension of the pet door. Also be sure to properly caulk and seal around the frame. Some people choose to build a frame to surround the pet door, if you do this, you’ll have to take the same precautions with sealing the wall to prevent water damage.

Alternative Rough Cut Method

This method can be easier in some cases than trying to go through both walls with one pass.

  • Step 1: Drill through the interior wall and draw lines connecting the outside part of the holes.
  • Step 2: Use a hand saw or reciprocating saw to cut out the inside sheet rock along the drawn line.
  • Step 3: Remove any insulation to expose the back of the exterior wall. Measuring very carefully and making sure all is level drill holes from the inside of exterior wall to the outside.
  • Step 4: Tape off the inside opening with a trash bag. This will prevent the dust and debris from going all over and makes clean up much easier.
  • Step 5: Make a mark from the inner side of the drilled holes on the exterior wall. It is a good idea to measure and level your outline from the outside, to ensure your hole will be the correct size.
  • Step 6: Use the pilot holes and a circular saw (use a concrete blade if you have concrete or stucco exterior) to cut out the exterior. Place a piece of cardboard under the saw to prevent it from damaging the exterior.
  • Step 7: Finish the opening with a reciprocating saw and if possible have a spotter inside.

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 2.5cm. 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 2.5cm wider than them.

Will this work for walls thicker than 20.32cm?

For walls thicker than 20.32cm, you can build your own tunnel out of wood or sheet metal.

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 durable aluminum.

Best Dog Door Hands Down

I bought this door in 2016 for my dog who needed outdoor access while I was working 10 to 12 hour shifts. It's lasted remarkably in our hot/cold area. Did have one issue with the exterior flap coming apart at one seam, so I called customer service, explained the issue, and had a set of replacement flaps at my doorstep within a week, free of charge. All around amazing company and products.

Very durable

We have the double flap wall mount. It has held up very well to our 3 german shepards of which go in and out it a LOT. This is expensive but you don't have to worry about it. The only maintenance I've done is clean in between the flaps in the wall which by design will collect hair and dirt. Not a big deal. We've had it for about 6 years now.

Medium wall dog door

This was an insane 5 hour project. Following the directions to a T. The long screw heads stripped WAY too easy, trying to get one out to try to get a straighter hole, it snapped. So then trying to figure out a way to rig up some sort of solution. Got some washers and nuts, but now the decorative buttons are useless to try to make it look better. The directions of cutting the tunnel 1/4” shorter than the wall, left an almost 3/4” gap and now we have to figure out a way to build up the tunnel and make it weather proof/air tight. The directions need to specify to install it against the house outside, not on the siding. There is no way to snug it secure over the siding, especially with the tunnel too short and the long screws breaking. A bit disappointed with paying over $500 for a dog door and having to ‘make do’ and rig up alternate ways to install it to make it work. Now just to train the dogs to actually use it. Living in Wisconsin, I hope that I don’t regret even more, spending this amount of money, and it will be worth it. Questioning that decision tonight! Sharon Wagner

Great Dog Door

We bought the Endura double flap dog door to replace a non-premium dog door I had installed in the wall several years ago. The old dog door began to break soon after it was installed, and it had large gaps that let air flow freely through the dog door. The new Endura dog door was easy to install. It required a slightly larger wall opening than the prior door, but after a few cuts in the wall, the new Endura dog door slid in, as did the bolts that run from the inside flap to the outside flap. Although we live in a relatively mild climate, we installed a double flap model. The old dog door had two flaps, and I didn’t want the outside of the new dog door to be flapless (with only an inside flap). The magnets for the Endura dog door are much stronger than those on our old dog door, so it took our three small dogs about a week to get used to it. (I think the dogs initially thought the dog door was closed because the Endura flaps do not swing freely like the flaps did on our old dog door.) I am very happy with our new Endura dog door, and I’m glad that I didn’t replace our old dog door with another inferior dog door that would break shortly after being installed. I can tell that this new Endura dog door will last a very long time.
