Duraflex: The Most Ingenious New Pet Door on the Planet!

They provide toughest, highest quality, best sealed pet doors on the planet! Our ingenious, new patented design uses super strong, rare earth magnets and an ingenious floating seal system to withstand winds up to 50 mph! Yet, the flap may be easily pushed open by even a puppy. The secret is in the use of multiple point magnets placed all along the periphery of the flap. Wind tries to push open the panel by pushing against all magnets at once requiring a great amount of force to break the air-tight seal. However, the nose first approach of a pet pushes against only one pair of magnets at a time allowing your pet to easily push the flap open.

Duraflex doors are professionally engineered to last a lifetime with a high strength aluminum frame, tough vinyl flap, industrial finish and stainless hardware. Even compared to the most premium brands, Duraflex provide better durability, quality, features, performance and style. You won’t find a better pet door value on Earth.

The Large size flap measures 10. 1/2” X 21 ?” to accommodate most dogs up to 90 lbs. Installs easily in any door 7/8” to 1 1/8” thick. This model includes a telescoping, aluminum wall tunnel for easy installation in any wall up to 7 3/8” thick. For very thick walls, you can add additional tunnels for virtually any depth required. No other pet door on Earth compares to the revolutionary new Duraflex!
