Mortise lock replacement for sliding door

Question

Hoping to get some help on finding the correct replacement part for this mortise lock for my sliding glass door.  There are no markings/part numbers etched on the lock, so difficult to confirm.  Thanks!

Thanks for posting. This mortise lock looks like our 82-218. Please compare. If you need a new face plate also, we offer versions of this mortise lock that include it: see our 82-226 or 82-227. The difference between these two mortise locks is the hole spacing on the face plate, so do compare with your old lock if you choose to go this route to ensure you pick the right option.
