Silverline series 7451 awning window locks

We have a bunch of different locks that look like this, but I'm not sure which one to recommend. It depends entirely on the size of the locking fork itself, which is obscured in your photo.

You can start by looking at our 38-096 and 38-095. One of these may be what you need but you will need to compare our dimensions to yours to confirm the better match. You won't  be able to do this without removing the original.

Thank you! I recognize this now, but it's bad news. This is an old lockset we carried many years ago that was since discontinued. We don't have anything that can replace this, unfortunately, and I don't know who else may carry it. I apologize for the inconvenience.
