This is a basic window latch to keep the window from sliding up. There are no names, numbers or markers. I think this was a replaced part. Photo 4 has the dimensions and the other photos are the front, angle and side profile the best I could get them. I wasnt able to take it off. I hope yall have it. Thank you.

Please see new SWISCO product code 90-293, sash lock, and compare it to your latch. Let us know what you think!
