Sliding door lock is missing

Thanks for posting. Unfortunately it's pretty difficult to say what you need based off this information alone, as hardware varies greatly even among brands. Is there a picture of the handle set or keeper that the lock is supposed to interact with that you could show us? Can you also show us the space where the missing lock is supposed to be? Those details might help narrow down what you need. Many thanks.

Thank you! Start by looking at our 82-265. I can't say for sure without the original as reference, but it's definitely worth considering. Let me know what you think.
