Replacement Flap Kits for Pet Doors

Our replacement flaps are available in our 11 standard sizes or we can make you a custom size flap. Please see our sizes page for more information if you need help in choosing the proper size. Please choose a size from the drop down box. The dimensions listed next to each size are for the passage opening the pet would use.  For rough opening and tip to tip frame dimensions, see our sizes page. If you need a custom size flap, please see our custom models information page.  You should have also received a "blue sheet" with your original pet door order that has your custom sizing information on it.  You can order a custom size flap by calling 800-646-4773.
