Ideal Pet ProductsDeluxe Aluminum Pet Door with Telescoping Frame, Small, 5" x 7" Flap Size

It's very difficult sometimes to find an aluminum pet door. Most are plastic. This is quality, and won't be as likely to crack when exposed to winter temperatures. Plastic sometimes freezes and cracks. This is all aluminum. The magnetic strip at the bottom of the flap is a full magnet, not just a couple of little ones. This one does not have a lock switch like many do. It actually has a slide panel you slip in and locks down for security. This eliminates the problem of those locking switches being triggered by your pet because most of those are below the flap and can be moved out of your settings. You lock this and it is locked, or remove the slide panel and your pet comes and goes. I recommend this over any of the plastic models and over those with lock switches (like the multiple settings). Also, this one was purchased for a cat. It was not installed in a door, but we cut two 3/4 inch thick plywood panels measuring the length to fit in our window channel the window slides in and a height of 16 inches, used construction adhesive to put the panels together. Once the adhesive dried, we installed the pet door into this panel of plywood. During installation, we insulated any open areas inside the frame between the wood and frame just to ensure no cold air leaks. After installing the pet door, the plywood panel was set into an open window, the window pulled down on top of the panel, then secured the window with a metal 'L' bracket so it could not be raised. Outside the window we built a platform for the cat to exit onto, and attached small 1 foot square shelves on the wall outside stair-stepped as a help for the cat to reach his platform. This installation allows us to remove it should we become petless for any reason.

It’s just what was needed in our garage door to permit the kitties to come in out of the cold.

This door was easy to install and works well, even the cats like it.

Great product. Easy and durable. Highly recommend!

Really works well for our kitties going in and out of the garage

Good product for a little pet.
