Who It's For

This replacement flap is best for pet owners who already have a PAC11-11039 style pet door and need a direct replacement that restores function quickly. It suits homes where the original frame is intact and only the flexible flap has aged, cracked, or torn.

It is not intended for shoppers who need a different size or a full-frame replacement; anyone unsure about compatibility should verify the 10 1/8 in x 16 7/8 in dimension before buying. Larger or custom pet doors will require other parts or models.
