Window Lock for a Jeld-Wen Casing
Hello there!
Thanks for reaching out to us. We'd be happy to look into this. Can you remove the lock from the window and show us a few photos? From there we should be able to narrow down some options.
Is there an identical window in the house with an intact lock that can be removed? If so, we can use that as a reference. In the meantime, we've posted a video below that may be helpful.
At this point, we can only offer an educated guess. With that said, the 38-095, 38-096, 38-138, and 38-139 come to mind but we don't know if any of them are what you have. Take a look at the specifications and see what you think. Note that the dimension of the projection of the fork is very important.
