This Door Mount model is designed specifically for doors where standard pet doors are too deep to fit properly. It provides a clean, stable installation in thinner door panels, making it a practical solution for interior doors, garage doors, and other narrow constructions.

A More Controlled Seal
Magnets along three sides of the flap help it return to a closed position after each use, creating a more consistent barrier against wind and outside air. This added control helps maintain a more comfortable environment near the door, even in changing weather conditions.

The flap is constructed from a polyolefin-based polymer that stays responsive across a wide range of temperatures. It remains flexible in cold conditions and resists deformation in heat, allowing pets to move through easily while maintaining proper closure.

The aluminum frame provides a durable structure that holds up over time, even with frequent use from active pets. The taller, narrower flap shape supports a variety of pet sizes while maintaining a balanced, functional design.

Security When Needed
A locking cover is included to secure the opening when the door is not in use. The construction provides a more substantial barrier, giving added control over when and how the pet door is used.

Adjustable for Pet Comfort
Magnet strength can be adjusted to better match your pet and environment. This allows for an easier push-through for more hesitant pets while still maintaining a reliable seal when conditions require it.

Made in the USA and backed by a lifetime warranty, this pet door is built for consistent performance and everyday reliability in homes that require a thinner door solution.

Single Flap Door Mount

Step 1 Prep Your Door

  • If you have not yet measured your pet, watch this video to ensure the pet door will work.
  • If possible, remove the door from its hinges using a screwdriver and hammer to tap out the hinge pins. Lay the door flap for installation. Tape the provided template to the door. The top edge of the cut-out line should be at least 3” (7,6 cm) above the pet's shoulders.
  • Be careful not to cut too close to the bottom of the door as you may reduce the door's strength. Level the top edge of the cut-out line.

Step 2 Drill the Holes

  • Once you are certain the pet door will work with your door, make sure the template is level, and mark the outline with a pencil. Remove the template and drill holes through the corners just inside of the lines using a ⅜” (9,5 mm) drill bit.
  • Make sure your drill is kept level and drills all the way through the door.

Step 3 Saw An Opening

  • Using a jigsaw, cut along the marked lines, making sure to cut straight.
  • We recommend applying masking tape along the outside of the lines to protect your door from scratch marks as you cut with the jigsaw.

Step 4 Check Weatherstripping

  • Ensure the weatherstripping is firmly pressed in the groove on both frames. Weatherstripping indicated in red.

Step 5 Position the Frames

  • Place the trim frame on the outside of the door and the flap frame on the inside.

Step 6 Position Screws

  • Select appropriate screws and insert them into the pet door from the inside.
  • Do not fully tighten screws until all four screws are inserted and the pet door is leveled.
  • Use the included installation magnet to help align the screws.

Door Thickness Screw Length
1/2" to 3/4" Short Screws (1")
3/4" to 1" Medium Screws (1-1/4")
1" to 1-1/8" Long Screws (1-1/2")

Step 7 Screw Door Into Place

  • Once the pet door is leveled, tighten the screws so that the weatherstripping compresses.
  • Do not overtighten.

Step 8 Attach Screw Covers

  • Push the four screw covers in by hand to cover the screws.

Step 9 Seal With Silicone

  • Apply silicone where the two frames meet. Also apply silicone where the outside frame meets the door.

FAQ

Are the panels/flaps 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. It remains flexible in temperatures as low as -40°F.

Is a single flap enough for winter weather?

A single Endura Flap is extremely energy-efficient and capable of withstanding winds up to 50 mph. It is the only door which allows you to increase the magnetic strength for increased wind resistance. It is recommended for timid pets. The double flap increases the energy-efficiency further.

Does the door sound very 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.

I do not have to contend with wind or rain, if I buy the single flap version of the wall dog door is it possible to add the second flap in the future?

It is possible, but it's not simple and can be quite costly. You will need to purchase a new inner or outer frame with the flap as single flap and double flap frames are built differently.

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 frame. If you purchase a single flap, the locking cover is on the interior frame.

Other brands of pet doors with plastic flaps always warp and thus let in air. How do these flaps hold up over time?

The Endura Flap is made with a special polymer called polyolefin. It remains safe, soft and flexible in temperatures as low as -40°F. It does not yellow nor harden in the sun. The patented magnetic design ensures the door door seals well for years. In fact, the pet door and flap are backed by a Lifetime warranty. To contact Endura Flap for door warranty email a photo to our customer service team, and we can take a look and let you know.

Does this door seal tightly against the frame so air and mosquitoes can't pass through. If so, does the guarantee cover that lasting, as well?

The double flap door mounts come with a tube of silicone that can be used to seal the edges around the frame. NOTE: single flap door mounts do NOT come with silicone. The warranty does not cover any accidents or damage made by improper installation.

Is this a good dog door for garage door installations?

You can install this in pretty much any door application under 1-1/8" thick, however most doors from the house to the garage have a fire rating so you need to check your local code to see it installing it is allowed.
