Custom Flaps & Parts for Your Pet Door

If you need a replacement flap for any dog door or cat door, locking cover, or other pet door parts, it is vital that you order the correct brand. Most parts are not interchangeable between brands or models from the same manufacturer even if the dimensions seem to match. Use dimensions to select the correct size within the brand only after the brand has been established.

However, in very specific cases there is inter-changeability.  There's miscellaneous weather-stripping, charley-bars and, of course, the absolutely essential Bug Warden--for those of you who already have a sliding glass dog door and want ventilation on warm days.

Shop our selection of custom flaps, collar keys, wall liners, locking covers, bug blockers, frames, and more. If you can't find the brand you're looking for check out pet doors manufacturer's page or contact our customer service at 800 826 2871.

Replacement Flap FAQ's

View our full list of pet door flaps here.


Q: Why is the double flap Endura door 1" shorter than the single flap version.


A: The single flap and double flap sizes are identical. The only reason we say the double flap is shorter is because you have 2 flaps that touch each other as the pet is going in or out so you lose about an inch of space up at the top.


Q: My Endura Flap wall mount is too heavy for my smaller dogs to push open. Do you have a flap that is easier to push that I can replace it with?


A: Flap are not interchangeable. If your smaller dogs are having difficulty pushing the flap open, you can adjust the magnet strength by removing the magnets. Here is a link to an instructional video demonstrating how:


Q: How do I determine which size flap to get for my pet?


A: We suggest that you measure your pet from the bottom of their feet to the tallest part of the back for height. For width you can open any door in your home wide enough for the dog to walk through comfortably. More info on how to measure your pet properly, please visit this link:


Q: Why would I need a double flap door?


A: For customers living in a mild climate, a single flap pet door would be suitable. However, if you live in extreme weather conditions, such as extreme heat or freezing, for prolonged periods, the double flap would be ideal. The double flap provides extra insulation from all weather conditions.
