Keep your home feeling comfortable even in extreme temperatures with the PetSafe Extreme Weather NEVER RUST Pet Door. When the temperature skyrockets into triple digits or drops below freezing, it will continue to let your furry friend come in and out while also giving your home maximum energy efficiency. Over three times more efficient than single flap doors, this pet door blocks severe temperatures with three flaps—including a center insulated flap for added protection against the weather. Installation is a do-it-yourself project and you can paint the white frame to match your door’s existing color. Rest easy knowing your pet can come and go, no matter how cold or hot it gets outside.
