The Endura Flap Pet Door for Doors offers premium performance for pet access without compromising insulation or style. Designed for interior and exterior doors, it accommodates single flaps for doors up to 1-3/4″ thick and double flaps for doors 1-5/8″ to 2-3/8″ thick. Its sleek, durable aluminum frame is available in white, black (bronze), or tan, blending effortlessly into any home decor.
Engineered for extreme climates, the polyolefin polymer flap withstands temperatures as low as -40°F without warping, while the magnetic seal along three sides blocks drafts and wind gusts up to 50 mph.  Even in the coldest of climates, the Endura Flap Pet Door has exceeded expectations, keeping drafts and cold air out, while remaining easy to clean and able to withstand active pets running through at full speed.
The flap’s taller, narrower design is ideal for multi-pet households, allowing pets of different sizes to share one door.Â
The customizable magnet strength offers flexibility for pet training and insulation value. More magnets can be added to increase the windproof seal, while magnets can also be removed to make the flap lighter for timid pets.Â
Security is paramount, and the included heavy-duty locking cover—equivalent to 16-gauge steel—keeps your home safe when the door isn’t in use.
Built with premium materials and backed by a Lifetime Warranty, the Endura Flap is designed to withstand active pets and harsh weather conditions for years to come. Experience the difference of a pet door that delivers durability, energy efficiency, and style in one high-performance design.

Please Note: If the magnets seem too strong for your pet, you can remove some of them to better suit their needs. On some sizes, they may need to be replaced for proper insulation. Refer to the video called Removing Side Magnets in the Videos section.
