Hakuna Pets Patio Pet Door Screen Insert Panel for Sliding Doors, Fits Door Track Min Ht 61.02" to Max Ht 84.25", UV Resistant Mesh, Locking Magnetic Dog Door, Easy Install and Removal, Medium, Black

Do his job for my cats. One have it right away and other catch it later, lol. Easy to ajust to fit good. The only thing is that ther's no lock to block the swing door when I don't want them outside.

This product caught my eye because my dog could go in and out when he wanted, plus the mosquitoes cannot come in. It was a great fit.

This product was very good quality - but it didn’t extend long enough to fit our sliding glass door frame, and it didn’t have a pet door that locked. Ultimately I had to return it!

Took a gamble on this purchase, and it paid off fairly well. I inserted this screen panel to connect to my sliding screen door. The fitting was not 100% seamless--where the top half screen extension begins from the middle on up, there is about a 2mm gap between my sliding screen door and the panel insert (see pic.) But, I'm lucky to have a door design that allows it to fit good enough... Take your door measurements first before purchasing. I give this an 8.3 out of 10.

This door piece works the way it is supposed to. We have to tape the flap open, because our cat won’t go in and out unless it’s opened. Otherwise it works the way it’s intended, and it’s a lot cheaper than the glass versions. But, you have to be very careful removing this, if you are taking it out of the door jamb, and lose your grip, it falls out the door. That causes the very bottom piece to snap. If the side pieces were a solid unit all the way to the bottom, this problem wouldn’t happen.
