Single Flap vs. Double Flap
Single Flap: The Endura Single Flap Door Mount is designed for doors ½” to 1-¾” thick. It provides excellent weather protection for moderate to harsh climates. The single flap doggie door is ideal for those looking for an insulated pet door that is light enough for cats and small dogs. The Patio Pacific pet door magnets are adjustable as well for easier use if needed.
Double Flap: The Endura Double Flap Door Mount is designed for doors 1-¾” to 2-¼” thick. For severe climates with heavy snow, rain, or wind, the double flap Endura dog door provides an extra layer of insulation to protect your home. Always measure your pet to ensure the proper 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 the flap 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 pet door.
Environmentally Friendly: The non-toxic Polyolefin Polymer dog door 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 exterior and interior dog door 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 dog door 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 doors. The 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

Where can I install the door mount pet door?
You can install the Endura Flap Door Mount in solid-core doors, hollow-core doors, metal doors, and storm doors. For doors more than 1-¾” thick (for the single flap), or 2-¼” thick (for the double flap), you will need a Wall Mount.
Can I install the pet door on an uneven surface?
Yes, the Endura Flap Door 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 size hole will I need to cut into my door to install a pet door?
See the “Rough Cut Out” column of the size chart on the Single Flap Door Mount or Double Flap Door Mount pages to find the dimensions of the hole you will cut in your door. Cutout size will depend on flap size, see this flap size reference chart for more details.
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.
Are there Endura replacement flaps available?
Why is there a difference in flap size for the single and double flap models?
As your dog walks through the double flap, the first flap hits the second one. Since each flap is ⅞” thick, the combined thickness of the two flaps takes up some space, accounting for a loss of about 1” at the top 1" of space a the top as they enter or exit.
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 too. 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.
