A quick learner from USA says:
We have having trouble with our patio sliding lock systems and need to replace locks of the two sliding doors. Please let me know what would the right size and models with price.
I have attached few photos of our original hardware of the patio sliding doors. Actually, we need two sets of the same size and model. I would appreciate if you could let me know your thoughts as quickly as possible. Thank you.

Hello! I believe either our 82-073 or 82-074 could work for you, depending on the thickness of your door. However if the thumb latch is the only thing that's broken, our 82-107 may be what you want.
