Review on Large Breed Locking Pet Door by Robert Patton

The large pet door worked great. All I had to do was modify the original opening a bit and add a new door and I was good to go. The new door is solidly built and I love the clean window style in the door as well as the magnetic stops on the bottom that ensure a perfect close every time insects can't get to the open position. I expect this door to last a lot longer than a door with three plastic flaps on top, which in my experience only last a year or less. The flap of this door has two pins at the top, which allows the door to move more freely. .
