These latches are for existing replacement windows.

We may be able to supply a replacement for the lock, but not the keeper. That contoured base is very peculiar and not something we'd be able to supply. You would need to contact the original window maker for that.

If you were interested in a match for the lock, at least, please tell me the distance between the two installation holes, center-to-center. We can then check our inventory for a match.
