The Endura Flap Pet Door for Doors is a high-performance pet door with unbeatable thermal quality and durability.

Installing into both interior and exterior doors, the Endura Flap is engineered with a versatile design built to maximize energy efficiency while giving your pet unrestricted outdoor access.

The single flap option fits in doors ½” – 1 ¾” thick, and the double flap fits 1 ¾” – 2 ¼” thick for added insulation.

Engineered with UV-retardant polyolefin polymer flaps, Endura Pet Doors are proven to withstand winds up to 50 mph and temperatures as low as -40 degrees Fahrenheit to keep your electric bill down during extreme winter and summer weather.

Available in sizes Small – Extra-Large with the option of black, white, or tan frame colors, the Endura Flap Dog Door is sure to meet your pet door needs.







The polyolefin polymer flap is lined with magnets on three sides to ensure that the flap stays shut in winds up to 50 mph. With variable magnetic strength, you can adjust the strength needed to open the flap—perfect for severe weather protection or for training timid pets.

Complete magnetic seal keeps the flap closed and helps resist energy loss in temperatures as low as -40 degrees Fahrenheit. The Endura Flap Pet Door is the superior option for household energy conservation and the utmost weather resistance.

Endura Flap Pet Doors are proudly manufactured in the USA. The strong aluminum frames and tunnel combine for extra durability. Included with every Endura Flap Pet Door is a sturdy ABS plastic closing cover to lock the pet door when needed. Lockable pet door ensures maximum safety and security.

Measuring Your Pet

Measuring your pet’s height correctly is crucial in ensuring you purchase a flap they can comfortably use for their entire life.

You need to keep in mind how high off the ground the pet door will be installed; this space between the ground and the bottom of the flap is called the Step Over.

The Step Over should be as low as possible for your dog to go through comfortably, this will make it easier for your pet as they get older. The Distance from the Floor to the Top of the Flap should be at least 1″ higher than the tallest point of your pet’s back.

Step Over + Flap Height = At least 1″ higher than the tallest point of pet’s back.

We recommend replicating the dimensions of your planned pet door installation on cardboard and seeing if your pet can comfortably go through it.
