This is my second dog door from this company and I've always needed an extension tunnel. It fit perfectly in my previous home. In my new house, this is also not suitable due to the styrofoam insulation. I could use 1/4 to 1/2 inch more. We've resorted to duct tape on the inside and the dogs are okay with it and it's durable.
