Myself and my son have been buying replacement flaps for years for our MaxSeal Doors.

We have had our dog door for almost 10 years. Our 2 dogs run through the door at top speeds and the original flaps finally tore at the mounting grommet. We ordered the replacement flaps and they were cut a little too small and the flaps didn't seal. I contacted Security Boss and they replaced them for us. I installed the new ones and they fit perfectly. I hope we get another 10 years out of these ones. Highly recommend this dog door.

This door is very well made and durable. I have three dogs who go in and out all day long, and I didn't have to replace the flaps until seven and a half years after installation! Replacement was easy and it's as good as new.

Exactly fits, no adjustment needed. Does require quite a bit of patience to install. Removing the old screws was more difficult than expected, and aligning the holes and reinserting new screws was a bit challenging, but I am very happy with the results. Worth the effort.

Old ones were a pain to remove. New ones went on like Donkey Kong! Next time I will buy the hinged ones. That might be 3+ years!

My son and I both have been using these dog doors, with double flaps, for years. Couldn't be happier. Quick service and good prices

They fit great and easy to install. I’m extremely happy with the door for one but the fact I can get replacement parts is fantastic!!

Appreciate the secure packaging and directions. Good job thank you

We love our Security Boss dog/cat door!! We've had the original flaps w door since 2013!! 8 years and they still work great. One tab hole ripped thru so we replaced the whole set. These replacements will outlast our pets. Great product!
