Having a new front door flap can really increase the curb appeal of a pup’s home. The Extreme Replacement Flap is a tinted single flap that has 2 sets of magnets along the sides and at the bottom to keep the door securely closed. Compatible with Extreme Dog Fence Pet Doors, our Extreme door flaps will keep your pet door securely closed again.

2 magnetic sealing flaps on both sides and also at the bottom provide even more energy efficiency by reinforcing the barrier that separates the weather outside from the temperature inside.
