Sliding Door Lock Latch

Thanks for you post! You may be able to use the 82-080 Mortise Style Handle Set but I can't make any guarantees given the design on your handle's mounting plate. Carefully look over the dimensions and the design to determine if this might be a suitable replacement for your repairs.

The mortise lock you have is likely the 82-268B Multi-Point Mortise Lock. You'll need to remove it to confirm that this is the right fit.
