The Endura pet door is a very weather tight and energy efficient, wind resistant doggy door for installation in doors. It can be had in single and double flap options, now available in white, bronze, and beige.

In a wind tunnel test, the medium size with a single flap held tight and didn't blow open in a 50 mph wind.

We think this is as good as a pet door gets!
