Please note: Our flaps are designed for each model individually and the interior and exterior flaps are different. While they are the same size, the strikes and weather stripping are arranged in different locations to match up with the magnets in the door frame. Please make sure whether you need an interior flap, exterior flap, or both flaps before ordering. All replacement flap kits include replacement nylon weather stripping, magnets, a drill bit and screws at no additional charge to you. If you need assistance picking out the correct size replacement flaps for your pet door, please see the graphic and measuring instructions on our sizes page.
