Before You Buy
What Features & Functions Should You Compare Before Buying a Pet Door for Sliding Doors?
Not all sliding-door pet doors work the same way. Before you buy, compare how each system locks, seals, installs and works with your existing sliding-door system.
Feature to Compare PatioLock™ Others
1 Does the pet door lock to your wall-frame striker without screwing into or modifying the frame?

Why these checks matter: your pet door becomes part of your sliding-door system while it is installed. Before buying, check exactly how the product locks, seals, fits and removes — and whether your original sliding-door locks need to be altered or transferred.
