Where can I find this kind of replacement screen clip?

Nope. Try a habitat restore store.

Call the company directly. Did you have anywhere shows you the brand name it will make it easy for you to contact the company. Good luck!

They might be very hard to find. The clips on our screens that help remove them are busting off making it hard to get them out, so I'm going to have to get new screens made.

Try Amazon-the have just about every thing.

How old is the door? Chances are if it's old it's discontinued or changed. Use your imagination and make clips and even drill small holes to screw them in with sheet metal screws. I had a Pergo floor that I got 80% finished and when I tried to get more product they said call this number they have plenty of it. I called, gave them the number and was told they had no way to check. Also they changed the locking mechanism in 2013. I asked them if they had a sample of a board to match up (hazel Oak) and was told to try Home Depot. Well they didn't have it. My next step is to tear everything out and start over with another brand. Any suggestions?

If you find them PLEASE let me know - we recently purchased a house with no screens. I called a company to replace them and was told that the clips are no longer made and without the clip I could not get screens! So frustrating

A lot of those are OEM. Made only for the manufacturer. If you can't find them you probably have to make generic clips work.
