Abstract
A locking system for a drawer file cabinet is disclosed. The system includes a locking assembly which is easily installed, removed and replaced without major effort and without major modification to the cabinet. This capability is provided through a novel arrangement of a cam plate pivotally connected to an insertable plunger lock, an internal support bracket uniquely adapted to receive and support and otherwise cooperate with the cam plate and plunger lock, and a reciprocating lock bar permanently mounted within a structural element of the cabinet. With the arrangement provided, only the cam plate and plunger lock are required to convert a cabinet incapable of being locked to a lockable cabinet.
