Not for a door, not for a wall, but for windows and sliding glass doors!
Now we have a door that covers every possible option. This one is designed to go on pane glass with the simple installation of only 4 screws. The flap is UV stabilized and made from high impact plastic. The flap closes with a magnetic clasp so the seal remains intact thus saving you money and eliminates drafts. The door can be locked into one of three different modes, in only, out only, or in and out. For a bit more security, upgrade to the magnetic cat door kit. This gives your cat a collar to wear that will automatically open and close the cat door behind him letting stray cats stay outside.
