We need to replace this as the lock is missing. The handle measurements are 7 1/8" tall by 1" wide. The plate on the edge of the door is 11" tall by 15/16" wide.

This looks potentially like our 82-078 handle set. However, the mortise lock that works with this handle set is no longer available. I apologize for the inconvenience.
