Parts

  • Inner frame with tunnel
  • Outer frame with tunnel
  • Locking cover
  • Inner wall template
  • Caulking
  • Sheet metal screws
  • 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 1 Measure Your Pet

how to measure your dog for a pet door
  • 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

how to check wall for studs, pipes, and wires
  • 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

align the template on your wall
align the template on your wall
add a bottom support stud between the wall studs to help secure the pet door
  • 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

Take the included Outer Wall marking Template and place it on the bottom left corner of the tunnel on the outside frame
Take the included Outer Wall marking Template and place it on the bottom left corner of the tunnel on the outside frame
slide the outside frame partway into the wall opening
mark the drill point
  • 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 straight through the wall at each location
  • 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

Level the jig
Level the jig
then mark its corners on your wall
grab the cardboard template and line it up with the corners you marked to trace out the cut lines
  • 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 the 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

Slide both frames (inside and outside) into the wall opening
  • 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

Get the frames leveled and aligned
Get the frames leveled and aligned
 drive two screws through the tunnels into the stud side
  • 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 the flap to ensure smooth operation.
  • 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!

Removing Magnets for Training with the Endura Flap



FAQ

How can I tell if this will fit my cat?

The simple way is to cut a hole in a piece of cardboard to the 6" x 11" flap size and see if they can get through comfortably.

Is the flap rigid?

No, the flap is flexible, it is just thicker than typical flaps.

Can you see through it?

It is kind of like a shower door, so you can see things through it, but can't really make out detail.

Does it come with a cover to lock it?

It does come with a cover that slides in on the inside.

If this seals so well will it be hard for my cat to use?

It is possible that you would need to adjust the magnets for training so check out our videos on this page for instruction on how to adjust those.

Will this keep one pet in while letting another out?

This is not an electronic door so any pets will be able to go in and out if they push hard enough. In addition, it will not prevent any stray and other animals like raccoons from getting in.

What if my wall is thicker than 8"?

The get the door mount version and have your contractor build the tunnel for you.

Is the flap on the inside of the wall or outside?

The flap is on the inside. And the pet door outside frame is designed so that the threshold on the bottom is lower than the one on the inside. This way if you do get any rain in the tunnel the water will evaporate or run out before it runs in.

Can I get a double flap?

We do have double flap doors, however, they are harder for smaller pets to push through so we don't really recommend them for cats.

Is the door loud?

It can be a little noisy when it closes, so it might not be the best choice for a bedroom if your kitties go in and out at night frequently.

I live in an area with hot summers and cold winters. Is this a 4 season cat door?

Yes! It has been tested in temperatures as low as -40° and as high as 110° Fahrenheit.
