Our most popular pet door, and for good reason. In wall pet doors are very attractive, efficient, and can be installed in many convenient places. These doors are the "bread and butter" of the pet door sales and installation industry. Double flaps that are separated by your wall, makes for a very effective weather barrier; as your pet enters one flap is closing as another is opening. A strong cover on the inside flap will increase security and peace of mind when not in use. Add to this a very attractive trim that comes in a variety of colors such as bronze, tan/beige, aluminum, and white. Lastly strong magnets will keep your flap from un-intentionally opening in strong winds. These doors come in 12 sizes to fit all breeds.
