Abstract: A cabinet is disclosed for storing planar sheets such as blueprints having a two stage door latch mechanism. The latch permits the cabinet door to be opened to a sort position wherein holding hooks supporting the hanging objects are in a closed position so that the sheets may be sorted through. The door can then be opened to a retrieval position corresponding to the holding hooks in the open position so that sheets may be added to or removed from the cabinet. In one form of the latch a slotted arm is pivotally attached to the door at one end and coupled to the back wall by a spring. A cam having an open slot is pivotally mounted to the arm at one end and while the other end is provided with a ball catch for locking the cam to the arm. A switch is constrained to move in the slots.
