The Classic PetSafe Pet Door has a Heavy Duty aluminum frame built to withstand the stress from even the most powerful breed dogs. Wouldn't it be great if your dog could open doors? It could go in and out when it pleases and you haven't locked the flap. If you are away from the house for any length of time, your dog now has access to the yard through your new PetSafe pet door. A closing panel is included so you can keep our pet inside and undesired visitors out. The PetSafe pet door is easy to install. Simply cut a hole using the template provided in the instructions and screw the two frames together. Now your dog is free to relax inside or outside.
