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.
Outer wall transfer template with level and pencil
Tools
Measuring tape
Electric drill/driver (philips head and drill bit for outer wall)
Safety gear
Stud finder
Drywall knife (or other tool for cutting the inside wall)
Saw (for the outside wall, pick one that works with your wall material)
Caulking gun
Clamp (or an extra set of hands!)
Take a few minutes to read these instructions from start to finish— it’s worth it! If the thought of cutting a hole in your house makes your palms sweaty, no shame in bringing in a pro to handle it!
Step 1Measure Your Pet
First up, measure your pet and mark the wall 3 inches above their height—it’s the sweet spot for lining up the template.
Don’t want to cut into the baseboards? If needed, adjust the height of the pet door so
you don’t have to cut them. Short-legged or mobility-limited pets may need a step added if you have taller baseboards. Consider how high your pet will need to step from both inside and outside the pet door, while still allowing clearance above their back.
Step 2Prepare Wall for Installation
Find a wall spot with a stud on one side and nothing scary like pipes or wires lurking behind it.
Once you’ve tracked down the stud, cut a little peek-a-boo hole and check things out with your hands—better safe than sorry!
Step 3Make the Rough Cutout
Line up the template with the stud, level as needed, and tape it down so it doesn’t go anywhere.
Trace the outline of the template. Once you’ve got your full template traced, remove it and finish cutting along the lines.
If you find insulation inside the wall, pull it out where necessary, but don’t toss it!
You’ll need it to fill in any open areas later.
Recommended (but optional): Before moving on, add a bottom support stud between
the wall studs to help secure the pet door. Pick a piece of lumber that fits your wall thickness, cut it to slide snugly between the studs (usually 14.5"), and lock it down with long screws driven in at an angle
Step 4MARK DRILL POINTS FOR THE OUTER WALL
Take the included Outer Wall marking Template and place it on the bottom left corner of the tunnel on the outside frame, where it will gently touch the inside of the outer wall. The outside trim frame has the larger tunnel, and no flap!
From inside the house, slide the outside frame partway into the wall opening until the Outer Wall Template reaches the exterior wall.
Using the small hole in the template and the provided pencil, mark the drill point.
Repeat this process for the top right corner: position the outer wall marking template, align it properly, and mark the spot.
Step 5DRILL THROUGH THE OUTER WALL
Once both points are marked, drill straight through the wall at each location. These holes will guide you when installing the outer frame in the next step.
If you use a 1/4" drill bit, the next step will be easier but any drill bit will work.
Step 6MARK WHERE TO CUT THE OUTER WALL
Head outside and line up the outer wall marking template with the holes you drilled earlier. Level the jig, then mark its corners on your wall.
If you need a little extra help lining things up, stick the drill bit in the hole to use as a pin. This works best with a ¼ " drill bit.
After marking your two corners, grab the cardboard template and line it up with the corners you marked to trace out the cut lines.
Then, remove the template and get your saw ready for the next step.
Step 7CUT OUTER WALL OPENING
Cut the outer wall opening using the appropriate tool for your wall type (e.g., stucco, siding, etc.).
Take your time cutting along the lines—it’s all about accuracy here!
Step 8INSERT PET DOOR FRAMES
Slide both frames (inside and outside) into the wall opening and telescope them together until snug against both walls. It is easier to insert the outside trim frame first, and this step is where an extra set of hands can be super helpful!
Step 9SECURE THE FRAMES TO THE STUD
Get the frames leveled and aligned, then grab a helper to gently squeeze them together from both sides of the wall. Or use a large clamp, which can also hold open the flap for you.
While maintaining this pressure, drive two screws through the tunnels into the stud side—position one screw about one-third from the top and the other about one-third from the bottom. This ensures a snug and secure fit.
Repeat on the other side, even if there’s no stud—it will still hold securely.
Step 10TEST YOUR WORK
Test the flap to ensure smooth operation. It should swing freely in both directions. If the flap catches at all, make adjustments before sealing the frame in the next step.
Step 11SEAL THE FRAME
To ensure your pet door is weather-tight and energy-efficient, follow these sealing steps:
Seal the Interior Frame: Apply a bead of silicone caulk between the interior frame and the metal tunnel.
Seal the Tunnel Seams: Apply a bead of caulk along the seams where the two telescoping metal tunnel sections meet. This will prevent air or water infiltration.
Seal the Exterior Frame: On the outside of your home, apply caulk between the exterior frame and the wall. Be sure to seal the top and both sides, but not the bottom. You want that open for water to drain out.
Seriously - don’t seal the
bottom, that’s your drainage zone!
Now, stand back, let your pet strut through their new door, and take all the credit. Well done!
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.
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 of?
It is made out of durable aluminum.
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. But you can view your options for in-glass pet doors here.

Thank you for submitting a review!

Moved to a new house so bought a new X-Large in wall. Works great but will say the new black tape for inside the wall leaves something to be desired. That could definitely be done better for a smoother look and feel (maybe an aluminum or even hard plastic insert instead). It is also pretty loud when the dogs go in and out but not sure what you could do about that. Great door overall with good quality but a few improvements would make it an excellent door.
We bought the XL size single flap dog door. Second day of use, the flap fell on one side. The bar does not stay put. For $650, this is ridiculous. Customer service hours are my working hours, so super inconvenient. I’m emailing them now, so I’ll see how it goes getting this replaced. Such a hassle…I guess I did not get what I paid for here.
I am having a dog kennel built and the contractor has not yet installed it. I haven’t even taken it out of the box yet . I would be happy to do an honest review if you were to ask me at a later date
I did a lot of research in purchasing merchandise and when I thought I was going have to return it, I got a prompt response. Turns out, I’m not going to return it; this makes me even happier!
