I needed a replacement Inside Frame for my doggy/kitty door. This door gets constant frequent use by both my small dog and my two cats. I didn't realize how inexpensive and easy to replace this part was, until I decided to look at the website. So happy I got it.

Had to replace the whole frame because magnet bars broke. Fairly easy to do except for lining up the screws. Would be easier with a vise, but otherwise completely doable. These doors hold up so well that it was AWESOME that I could just replace certain parts.
