This insulated replacement flap kit fits the Extreme Weather Pet Door™. The kit includes the insulated replacement flap, the flap clamp, the flap back plate, and the flap mounting screws. The insulated flap offers protection from extreme heat and cold, drafts, insects, and driving rain. The insulated flap does not fit any other models of doors.
This is the yellow middle flap in your pet door. If you need to replace the vinyl flaps on either side of the insulated flap, you will need to purchase a Replacement Flap.
