Hello. This piece of plastic snaps into the top of my vertical sliding window. The brand is milgard. It prevents the window from opening too far. I believe its called a sash stop, but I'm not certain of that. Its 1 1/2 inches wide. It has small "hooks" on the edges that I tried to get into the photo. It's 3 1/2 long, however I could cut that if I had the correct width.
I would like two of them please.
Thank you for your time.
