Replacement flaps for pet doors are unique for each manufacturer. You cannot substitute one type of flap for another, therefore one cannot upgrade from one type of flap to another as each model has unique connection points, design and sometimes even method of movement. Below you will see replacement flaps and images to help determine your particular pet door flap. Sometimes the measurements are slightly different from printed measurements, this is because some manufacturers will round-off the exact measurement. If you are uncertain or would like our opinion as to the flap you may need, please call our customer service team for assistance. We cannot guarantee our recommendations as we cannot see the exact unit you need to replace, but we are very knowledgeable and will help in any way we can.

NOTE: Pride brand pet door flaps have the same 2-piece design and are relatively the same size as their PetSafe/Johnson counterparts, with the exception of the small (customers modify the small to fit by cutting the "nubs" off on the top of the flap). Other sizes do not require any modification. Click here for the Pride Pet Door Flaps.
Special Note: PetSafe had discontinued these Pet Door Models - Flaps are also discontinued. If you need to replace your current 'Ultimate' or 'Johnson Pet Door' without revising the cut in your wall or door, we suggest you check out the MaxSeal Custom door. They can be made to fit your existing opening.

How to Maintain Pet Door Flaps
No pet door flap will last forever. Flaps are usually made of flexible vinyl, hard plastic or hard lexan. In some special cases you might have metal flaps as well. The follow information goes over ways to maintain your flaps so you get optimal use out of them.
Sizing & Placement of Pet Door
Golden Rule When Sizing a Pet Door
Select a pet door that when installed will clear the shoulders of the tallest dog by 1.5 to 2". The bottom of the pet opening should be low enough to the ground to allow easy step over navigation, even as the dog ages.
If a pet door is too small, then the dog is likely to pinch the flaps at the top of the pet opening, this causes stress to the flap at the connection point, and will result in you replacing flaps more frequency.
Keep Flaps Clean
The easiest way to clean your dog door flaps is with a warm water and mild vinegar solution. Grease cutting detergents can leave your flaps "sticky",
Tighten flap Connection Screws
Check how secure the flap is connected every few months. . Preventing a flap from failing is as simply as making sure it's attached securely. If you have multiple pets or even a pet that uses the door aggressively, screws can loosen. This will cause the flap to shift in-between the frame of the pet door and the screw with repeated use. Eventually this shifting flap will simply rip out and fail.
Overall Performance Check
Most importantly, don't forget about the dog door. Generally just checking the condition of the door once a month will extend the life of it. This way you can detect damage early and decide on the course of action to take.
