In the past, if you purchased the PetSafe Aluminum Wall Entry for your pet, you must know what a great product it is. The PetSafe Aluminum Wall Entry uses 2 flaps on either side of the tunnel for extra energy efficiency. One flap is in the inner opening and one is for the outer opening. The flap is a soft, tinted vinyl with a magnetic closure. The Deluxe Patio Panels have either one center screw or two screws above the flap. Remove the screw(s) and pull down on the flap or the metal flap holder. Slide the old flap out and slide the new one into the flap holder. Reinsert the flap holder into the frame and reinstall screw(s).
The flap for the PetSafe Aluminum Wall Entry door flap slides into a channel on the top of the frame. To replace the flap, the door must be removed from the installed surface and the screw (either on the right or left side of the top of the frame) must be removed. The old flap can now slide out and the new one will slide in.
