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.
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 frame has the larger tunnel, and
will not have the locking cover in it!
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!

How to Remove Side Magnets for Easier Use
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 since the larger flaps might be difficult for them to push through. However, if you have cats and dogs sharing an Endura Flap wall mount, you can decrease the magnetic resistance of the large flap's threshold to make it easier for cats to use. For small or medium pet doors, you can offset the magnets slightly to decrease the magnetic strength.
How do I know what flap size will fit my dog?
A perfectly fitted pet door will 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 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, door mount, kennel doors, window sashes, and sliding glass door patio pet doors).
What material is the Endura Dog Door for Walls’ telescoping tunnel made from?
It is made out of durable aluminum.
I think a wall mount will stand out too much. Is there any way we can blend it into the rest of my home?
We would recommend checking out the Endura Flap Designer Pro Series for walls. It comes with everything you need to install your pet door into your wall. The outer frame is also less prominent, which would allow you to install the trimming of your choice around the pet door. It is also available in a stripped-back kit for any skilled carpenters who want to build of their doggy door to their preferences.
The sides of my flap no longer touch the frame. What happened?
It sounds like the bellows have contracted. You can follow the instructions on our troubleshooting guide to learn how to fix it.

Tabs to secure outside framing and flap wasn't long enough to screw into the studs. I made up longer tabs myself to fix that issue. Other than that it was a simple easy install.
At my home in Texas I had a small Endura Flap Wall Mount Pet Door and loved it. I recently moved to Michigan and needed a dog door. So Endura Flap was my first choice. The doors work as designed and are very durable. They kept the Texas heat out and I never felt drafts when near the door.
Love it! I paid someone to install the door as I wasn't confident in my ability to do so.
My cats were already use to the idea of a cat door so they took to it quickly. They race in and out off to their catio when they have the zoomies.
I appreciate the small size, less of a hole in the wall. I am overall quite pleased with this cat door. :-)
