Which part do I need?

Question

I am needing a new lock for my sliding patio door. Please look at my pictures and let me know which lock I need. I think it is the replacement lock #82-211, but I am not sure.
Please advise.

From your photo, it appears that you have the 82-211 latch. Check your dimensions and make sure ours line up to yours. We also carry one that's a bit deeper; see our 82-214. Compare them with yours and see which one is better.
