Installation & Fit

  • Designed for straightforward DIY installation using standard household tools like a drill and jigsaw; consult a contractor if you are not fully comfortable with this type of work
  • The self-framing tunnel wraps the internal cutout for a clean, professional finish without custom carpentry
  • Requires a flat mounting surface on your door; avoid placing over deep decorative molding or glass inserts (if you have a French Door, the Utah Pet Access French Door Glass Insert may be better suited)
  • Ensure the flap width is at least 2 inches wider than your pet’s widest point for comfortable passage
  • Mount the top of the flap 1 to 2 inches above the pet’s shoulder to prevent crouching or back injury
  • Keep the step-over height as low as possible to accommodate your pet as they age or if they have limited mobility
  • Flexible mounting heights allow you to customize the opening to the specific height of your dog or cat

Best Suited For

The Endura Flap Pet Door for Doors is ideal for:

  • Extreme weather climates with very hot summers, or very cold winters
  • Door thickness of 1/2" to 2 3/8" (see the Endura Flap Pet Door for Thin Doors if your door is less than 1 1/8" thick)
  • Homeowners prioritizing durability and longevity: this door is covered by a lifetime warranty!
  • Solid-core, hollow-core, metal, aluminum or steel doors

Not Ideal For

  • Temporary installations or rental properties
  • Pet families with both large dogs, and very small dogs or cats, as the smaller pets may have difficulty with the heavier flaps (the Liberty Pet Door for Doors may be a better fit)
  • Thin Doors less than 1 1/8" thick Check out the Endura Flap Pet Door for Thin Doors.

Product Details

Product Details

The Endura Flap Pet Door for Doors is made for homeowners who want effortless pet access without sacrificing the comfort, efficiency, and security of their home. It is crafted as a premium door insert with a tighter seal and enduring construction compared to typical pet doors.

The Endura Flap is designed to help keep the temperature more consistent near the door and reduce unwanted airflow during stormy weather. The flap uses a three side magnetic seal that helps it close cleanly after each pass through and stand up to wind pressure that can work lesser flaps open. It is rated for wind gusts up to 50 mph.

Energy efficiency is built into the flap itself. The dual layer flap design helps slow heat transfer by using trapped air as a barrier, similar to the way an insulated window works. The result is dependable weather resistance in all seasons.

Security is paramount, and the included heavy duty locking cover, equivalent to 16 gauge steel, helps keep your home protected when the door is not in use. 

Fit should feel confident, not uncertain. This model is made for standard interior and exterior doors and is available in single flap and double flap configurations. Consult the size chart to choose the opening size for your pet and confirm door thickness so the frame seats properly and the seal performs as intended.

You can also tailor how the door feels for your pet and your climate. Magnet strength can be adjusted so timid pets have an easier push through, while windy conditions can be matched with a stronger closing seal. Adjustment guidance is provided in the Removing Side Magnets video in the Videos section.

Built in the USA and backed by a Lifetime Warranty, the Endura Flap is designed for long term performance you can trust.

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

  • 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!
