Single Flap vs. Double Flap 

Single Flap: The Endura Single Flap Wall Mount is designed for walls 2” to 8-¼” thick. It provides excellent weather protection for moderate to harsh climates. Since the single flap is lighter than the double flap, it is ideal for those looking for a dog door flap that is insulating, yet light enough for cats and small dogs. The magnets are adjustable for easier use if needed. 

Double Flap: The Endura Double Flap Wall Mount is designed for walls 2” to 8-¾” thick. For severe climates with heavy snow, rain, or wind, the double flap provides an extra layer of insulation to protect your home. Always measure your pet to ensure the proper doggie door flap size fit.


Locking & Security 

All Endura Flap Pet Door models come with a heavy-duty, molded ABS Locking Cover to block access to the doggy door flap when needed. The locking cover keeps unwanted critters out of your home and allows you to lock your Endura Flap Dog Door for Walls when you’re away for peace of mind.

Features of the Endura Flap Pet Door

Endura Flap Pet Doors are top of the line in quality, durability, and insulation value. All Endura Flap doors are made in the USA, designed and manufactured in San Luis Obispo, California. Check out the unique features that make the Endura Flap Patio Pacific dog door the best dog door

Environmentally Friendly: The non-toxic Polyolefin Polymer Flap is safe for your pets and the environment. Most pet door flaps are made of vinyl (PVC), one of the most environmentally damaging plastics to produce. The production, usage, and disposal of PVC releases toxic, chlorine-based chemicals into the environment.  The polyolefin polymer used for the Endura Flap is recyclable and safe. It is commonly used in food packaging, and its production does not produce any toxic fumes.


Award-Winning Flap: In addition to being environmentally friendly, the Endura Flap is made to withstand extreme heat and cold to keep your home insulated. Whereas most vinyl pet door flaps are about ⅛” thick, the Endura Flap is ⅞” thick. The sealed flap unit is slightly thicker than dual-pane glass and provides a similar level of weather protection.  The flap unit is translucent for maximum ease of use by pets of all sizes. The flap’s interior is divided by horizontal barriers to reduce the effects of air currents moving within this space as it continuously heats and cools.

Severe Weather Protection: Every component of the Endura Flap Pet Door was designed for extreme weather protection. The flap is treated with UV-resistant retardant, preventing shrinking, warping, or yellowing in the sun. It is attached to an architectural extruded aluminum frame for additional durability. All Endura Flap models, single and double flap, protect against temperatures from -40℉ to 110℉, as detailed in this energy performance study. In addition, magnets line all three edges of the pet door flap for 50 mph wind resistance.


Superior Manufacturing: The weather-resistant flap rotates on a rod instead of attaching to screws, preventing the warping and tearing common in standard pet doorsThe magnets lining the flap are customizable, meaning you can adjust the magnet strength for timid pets or for increased wind resistance. 

High-Aspect Ratio Flap: The safe, flexible Endura Flap has a high-aspect ratio. Most pet door flaps are not very high for their width, meaning you need to install the door higher up to accommodate your pet’s height. With a high-aspect-ratio flap like the Endura, you can install lower to the ground so that your pets can manage the step-over even as they grow older.  


Frequently Asked Questions 

How hard is it to install a pet door in a wall? 

Installing an Endura Flap wall dog door takes a certain level of skill since you will need to cut through your wall without hitting any pipes or wires. We recommend hiring a professional if you are not confident in your abilities. See the through the wall dog door installation page for more details. See our installation video archives to learn about other installation options.

What if my wall is more than 8” thick? Would that prevent me from installing an in-wall dog door??

If your wall is more than 8-¼” thick (single flap) or 8-¾” thick (double flap). You can build your own tunnel out of wood or sheet metal and attach it to the pet door frame(s). You would use this instead of the metal tunnel pieces included with the wall mount. 

Is the flap on the inside or outside for the single flap model?

The flap is on the Endura Flap pet door for walls’ interior frame (the one inside your house) for the single flap model. For the double flap dog door for walls, there is a flap installed on both the interior and exterior frame. 

Why is there a difference in flap size for the single and double flap Endura dog door for walls model?

Since each flap is dual walled making them 7/8" thick as the pet pushes through the first flap will actually hit the second flap. This makes it so that there is a loss of about 1" of space at the top as they enter or exit their Patio Pacific pet door.

Can I install the in wall doggie door on an uneven surface such as a brick wall?

Yes, the Endura Flap Wall Mount can be installed on uneven surfaces. You will just need to fill any gaps between the pet door frame and recessed surfaces with caulking to maintain insulation. 

What if I want to close the pet door at night?

Every Endura Flap Pet Door comes with a Locking Cover to block access to the flap when needed. 

What’s the difference between a door mount and a wall mount?

You can read about the difference between a Door Mount and a Wall Mount here. 

Are replacement flaps available?

Yes, we carry replacement Endura Flaps. See our full selection of replacement parts and accessories for more replacement options. 

What if I just need the wall kit?

We carry the Wall Kit here. It includes all of the parts required to mount an Endura Flap Pet Door in a wall.

Can cats and dogs share this door?

Yes, cats and dogs can share this door. However, we do not recommend flap sizes larger than the Small for cats, since these flaps are so insulating and heavy-duty. 

If you need a larger flap size for your dog, you can adjust the magnet strength so that your cat can use the door. Keep in mind that this will reduce the wind resistance of the flap. If you have a very large dog but want a door for your cat as well, you might consider installing another Endura Flap for Your Cat with a small flap size.
