If I could give this 0 stars, I would. While assembly was not difficult, the dimensions are not at all accurate. Our door is 96”, which means this should have fit easily. It did not. It BARELY fit, even with the springs completely compressed. It would be impossible to use in a door less than 96” tall. When we finally got it in place, it was a joke. The door didn’t even come close to lining up correctly and you could see daylight between the top and bottom sections, which came with pre-drilled holes from the manufacturer, so there was no way to adjust them. We tried adding the weather stripping to see if that would help and it was a joke. The dog door itself is HEAVY! There is no way our medium sized dog could push it open. While you can remove layers, there was no need for us to even try because the door left so many gaps up the side, that it was useless anyway. Given the price of $250, we expected a usable product at the very least. DO NOT BUY!!
