Older single hung windows in the house we bought that also have storm windows on the outside but two of our inside windows are missing the window latch and when the window is lowered the latch fits in a slot on the bottom of the window frame locking it. It is 2" long and 1" high with screws in the window rail (top) holding it to the window.

I'm afraid that I don't recognize this specific latch. I can tell you that this is an older style part that isn't widely used anymore. They're becoming harder and harder for us to get a hold of. I will do my best to find a match for you, I just wanted to let you know ahead of time that there are no guarantees.

Before I get started, can you remove this latch from the window and show it to me from a few different angles? I'd especially like to see the end profile. Thank you!

Thank you for your continued patience with us during this time. We believe you have an old Keller/Air Control window latch that has been discontinued, Therefore, we'd like to suggest having a look and possibly consider using our 90-012 in its place. Get back to us and let us know if you believe this would work on your window.
