Abstract
A locking system for a file cabinet which prevents opening of more than one drawer of the cabinet. The locking system includes a camming system which blocks opening of any secondary drawers after a first drawer has been opened. A rotatable cam having a hook mounts to an individual lock lever. The hook engages an opening in the file drawer or door to prevent retraction while also blocking the interlocking mechanism for the file drawers.
