MaxSeal Replacement Flaps

MaxSeal flaps are specific to size as well as their location of interior or exterior on your pet door. A interior flap will not line up correctly with the magnets of the exterior frame and vice versa. The magnet placement of both the interior and exterior of your pet door are designed to provide you with an optimum seal. Altering the placement of these magnet positions will affect the performance of your door. All Security Boss products are hand built to order.

Replacing your MaxSeal flaps is easy and can be done without removing the pet door frames. Thumbscrews located at the top of the flap can be loosened by hand or by Allen wrench (Provided in your hardware packet when you purchased the door). If you have any difficulty you can place a Flathead screwdriver behind the flap and apply some pressure to allow thumbscrews to catch.

*Note: Thumbscrews & Allen wrench are included with flap purchase

    Replacement flaps

    Posted by Isabell on Mar 5th 2021

    These are amazing. Easy to install and last a long time. Strong magnetic seal, so no worries about uninvited critters getting in. Good company and great communication. Buy these doors, they are the best. Not cheap plastic. We installed ours at least 15 years ago. This is only 2nd time we have replaced flaps. Highly recommend.
