MaxSeal PRO Pet Door for Doors

Best dog door ever

I have used these dog doors for probably 15 years. I have installed through the wall style and door styles. I have NEVER found a better door!

It seems to be very good quality.

unfortunately, I measured the opening but not the size of the actual pet door. I am having some problems with deciding to return it or have the door look bad from the former pet door.

Same high quality

Replaced an old battered door in minutes. Easy install and great quality
