A door locking mechanism is disclosed including a door locking member in communication with a lock-actuated bolt which selectively allows rotation of a rotatable actuator plate member. The rotating actuator plate member is attached to a rotatable handle and to a plurality of actuator bars which move locking bolts so as to selectively prevent opening of the door. The rotatable actuator plate member enables all of the actuators to be moved from a single location so that a plurality of cams, etc., are not needed to move locking bolts positioned about the perimeter of the door between open and locking positions. In an additional aspect of the invention, horizontally extending actuator bars are adjustably attached to elongate locking bars having a plurality of locking bolts attached thereto, so as to enable assembly of the locking structures of the door locking mechanism without assembly, and to enable interchangeability of parts.
