Installation Instructions
We suggest that when pre-cutting the rough for any pet door, that you add at least an 1/8" to the width and height to allow for easy fitting. Some Rough cuts are more precise and may fit tighter if the hole is not completely true.We always recommend that the door is on hand prior to cutting. We will not be responsible for re-fitting after the fact.

ONE TOUGH DOOR!!
I have spent a small fortune on dog flaps for different dog doors finally decided to just get the SB72 man this thing really works!! Dogs cant chew the aluminum clad flap on the exterior then the vinyl flap seals so well! Well worth the money!! Cant go wrong with the SB72 if your dog chews!

Built like a Tank
Wow..had my new SB72 door in for a week, it is one tough door, I love the rigid outer flap and the inside flexible flap seals perfectly.....I have absolutely no draft of air leak anywhere! Really glad I sprung for the extra cost, great product.
