  • Sturdy locking cover top-loads into the interior aluminum frame (for double flap units, you can opt for a second locking cover to close on the exterior frame as well)
  • Standard tunnel range fits many common wall depths, from 4-1/2" to 7-1/2" thick
  • We do recommend consulting a contractor if you are not comfortable with cutting into the wall of your home

Best Suited For

Ideal For

  • Homeowners who want a dedicated pet entry built into the wall instead of sharing a sliding door opening
  • Homes where stronger insulation and more stable hot and cold weather performance are a priority
  • Projects where a cleaner finished look on the interior side matters as much as everyday function

Not Ideal For

Are replacement flaps available?

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

How easy is it to clean the flap?

It is extremely easy to clean the flap. All you need to do is wipe it down with warm water and mild dish soap. Do not use any abrasive cleaners as you may damage the material.

How high off the floor should my dog door be?

Generally, every pet door should at least 3" off the floor to maintain your door or wall's integrity. The distance between the bottom edge of your pet door and the floor is called the step-over, and is an important aspect of determining how big of a pet door your dog requires. The step-over should be easy for your dog to "step-over," and never be more than a third of your dog's height. You can read more about step-overs in our measuring guide: /pages/measure-your-pet.

Product Details

Product Details


The Endura Flap Dog Door for Walls is designed for buyers who want a pet door that feels like a permanent part of the home. Once installed, it reads as a dedicated opening for the pet, with a more integrated look and a more substantial feel than temporary or shared-entry alternatives.

A cleaner wall installation experience
The major advantage of this model is the telescoping aluminum tunnel, which is built to adjust through the wall depth instead of relying on a separately fabricated tunnel. That built-in fit approach helps the installation come together in a cleaner, more predictable way and gives the finished result a more consistent look from inside to outside.

The aluminum frame and tunnel give the unit a rustproof structure that holds up well in daily use, and the overall design reflects long-term ownership rather than short-term replacement. This is the pet door for homeowners who desire something solid, serviceable, and made to stay in place.

The Endura Flap advantage
At the center of this wall door is the Endura Flap system, built for long-term performance and easier ownership. The dual-layer flap design uses a trapped air space to support stronger insulation and energy efficiency, helping the opening perform more like a protected part of the home in hot and cold conditions.

It is also designed to stay serviceable over time. The flap and key wear components can be replaced without removing the frame from the wall, which keeps maintenance simpler and avoids the disruption of reworking the full installation.

Made for the long haul
Made in the USA and backed by a lifetime warranty, this is a wall pet door built for pet owners who want a durable, permanent-feeling solution they can rely on for years.

Parts

  • Inner frame with tunnel
  • Locking cover
  • Caulking
  • Outer wall transfer template with level and pencil
  • Outer frame with tunnel
  • Inner wall template
  • Sheet metal screws

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 1 Measure Your Pet

Measure 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 2 Prepare Wall for Installation

Prepare 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 3 Make the Rough Cutout

Make 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 4 MARK DRILL POINTS FOR THE OUTER WALL

MARK DRILL POINTS FOR THE OUTER WALL

MARK 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 5 DRILL THROUGH THE OUTER WALL

DRILL 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 6 MARK WHERE TO CUT THE OUTER WALL

MARK WHERE TO CUT THE OUTER WALL

MARK 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 7 CUT OUTER WALL OPENING

CUT 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 8 INSERT PET DOOR FRAMES

INSERT 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 9 SECURE THE FRAMES TO THE STUD

SECURE THE FRAMES TO THE STUD

SECURE 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 10 TEST YOUR WORK

TEST 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 11 SEAL THE FRAME

SEAL 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!
