MaxSeal Replacement Flaps
Tall - 11"w x 20"h

Flaps come with Set of Thumbscrews

The MaxSeal Replacement Flaps will fit BOTH the door mount models and the wall mount models. The interior and the exterior flaps are unique because the steel strike plates are staggered in their placement on the flap. (This design is so that your flaps will seal better when in a dual flap model door).



MaxSeal Tall 11 x 20 Replacement Flaps

Note:If you have a single Flap model, please select the exterior flap for the size that you need. Customers with a dual flap model can replace either the interior or the exterior....or both.
