Product Overview

Pride Pet Door Flaps are two piece black rubber flaps that are direct replacements for Johnson flaps in medium, large and extra large sizes


Pride pet door flaps are black rubber two piece assemblies. The parts are not available separately, they are sold together. These flaps are generally quite durable and often times the flap size is completely worn off, in which case you will need to measure the flap to see which one you need. We measure the center part of the flap. If you measure the outside of the U shaped part of the flap you will end up with the wrong flap, so be careful.

Pride flaps are a direct replacement for Johnson and Pet Safe doors with 2 piece flaps for medium and larger sizes. Although this isn't the best picture, the Pride flaps have the same center flap and U shaped flap. M-2 or medium is the same as MD400A, L-2 or large is the same as LD500A, and XL-4 or extra large is the same as XLD600A.

We have had just a handful of out of hundreds of customers tell us that their MD400 flap didn't fit a plastic framed Johnson door correctly. The flap can be trimmed to work if you'd rather not replace the door. We did have one customer who said that the MD400 flap was too long for his Johnson panel pet door for a sliding door and he ended up returning it.

The S-2 or small flap is similar in size to the SD300A but mounts differently. You will have to trim the small flap and punch holes in the top to make it function.

Pride uses Masonite or pressboard locking covers, these covers do not fit Johnson doggy doors.

    Replacement flaps

    Posted by DEBRAH on Oct 6th 2020

    The only thing preventing me from giving this 5 stars is the fact that the flaps are not clear. The flaps I purchased were the second set of replacement doors for my original Johnson doggie door so my dogs were used to them being black. It is a perfect fit (if you order the right size). I inadvertently ordered the wrong size but The Pet Door Store was excellent at handling the return and quickly credit my account. The quality of the flaps is very good and durable I just wish the magnets stayed attached longer for a more secure fit. I would highly recommend this to people and definitely would purchase from The Pet Door Store. Awesome customer service, great job!

    It doesn’t really fit my old Johnson door. It is to large . I had to use my old putter flap.

    The Pride Replacement Flap Assembly arrived in a timely manner, was the exact replacement for our 20 year old screened porch doggie door, and installed easily. Very happy!

    Great product, only four stars because the holes were a little bit off from the ones in my door. I had to work the flap a little to screw it in.

    It wasn't as easy an install as I'd hoped--durn little screws kept getting away from me.!But it fits and is just like the old Johnson one which gave up after 22 years of service. I was delighted to find it.

    I find that the amount of frost buildup at the location of the metal clips is more pronounced than the the original Johnson door flap.

    Easy to install. Have had problems with the u shaped part breaking on the bottom corners . Probably due to the large dogs that run through the door.
