ABSTRACT:
A lock for sliding doors for cabinets and the like. A shoulder on a catch element carried by the door extends through a lock opening in the cabinet frame and engages the edge thereof to secure the door. A key of particular length moves the shoulder from the locked position to an intermediate position at which it can pass outwardly through the back opening. If the catch element is moved too far, a second shoulder engages the edge of the lock opening and the door cannot be opened.
