This latch was designed for and is being used on lavatory doors.
All SAM 10 latches are basically the same. A Couple such as the -62 are a little different in size. However, the major difference is the language. Here is a summary of the available configurations.
The SAM 10 series come in either a Right (R) or Left (L) configuration. If you walk up to the door, and the hinge on the right hand, the latch is on the left hand side, and the bolt of the latch moves towards the left when you lock, that would be a (R).
