Pet door is made of impact-resistant super-strong thermoplastic with a clear flap that allows your pet to see if the slide is in place. It features an inner telescoping frame that adapts to doors of 1 1/4" to 1 3/4" thickness, and there's the tamper proof mounting system so the door can't be removed from the outside. The floating bottom threshold provides a perfect seal every time. Installation is a simple four step process that takes an average of only 20 minutes. Limited lifetime warranty. Flap opening measures 15" x 20".
