An apparatus and method for enhancing the security of a cluster box unit which includes a protective enclosure, internal cabinetry, door, hinge and locking system. The cluster box unit may also include outgoing mail compartment doors that are heavily constructed and rigidly reinforced, with the locks carried thereon protectively shielded, and with the extensible bolts of these locks being engaged by brackets that not only lock the outgoing mail compartment doors but also the master loading doors of the cluster box units. The cluster box unit may also include master loading doors are provided with hinges that extend the full height of the doors—hinges that are defined by pivotally interfitting elements of extrusions that very sturdily mount the master loading doors, that prevent prying or bending the doors in the vicinities of their hinges. The interfitting elements of the hinge extrusions also permit the doors to be installed on their surrounding door frames quickly and easily, and permit one or both of the master loading doors to be quickly and easily removed for service or replacement when necessary.

1. A cluster box mail delivery unit locking system for retaining a closure in a closed position, comprising: a cam latch connectable to the closure for pivotal movement about a first pivot axis between a latched position and an unlatched position, the system including a strike for engaging with the cam latch in the latched position, and disengaging from the cam latch in the unlatched position;a key-turnable member connectable to the closure and connected to an operating arm for pivoting the operating arm relative to the closure about a second pivot axis spaced from the first pivot axis between a normal position and an operated position;a linkage coupled to the operating arm and the cam latch for pivoting the cam latch from the latched position to the unlatched position in response to pivotal movement of the operating arm from the normal position to the operated position, and for pivoting the cam latch from the unlatched position to the latched position in response to pivotal movement of the operating arm from the operated position to the normal position, wherein the linkage is coupled to the cam latch at a single point equidistant to the first axis in the unlatched position and the latched position, the point rotated around the first axis;a mounting member connectable to the closure for defining an externally threaded surface that extends substantially concentrically about the first pivot axis; andan internally threaded passage formed through the cam latch and configured to be threaded onto the externally threaded surface of the mounting member for mounting the cam latch on the closure for pivotal movement between the latched and unlatched positions. 2. The cluster box mail delivery unit locking system of claim 1, comprising spring members controlling the operating arm to pivot from the operated position to the normal position to pivot the cam latch from the unlatched position to the latched position. 3. The cluster box mail delivery unit locking system of claim 1, comprising a lock having a releasing mechanism for the key-turnable member pivoting the cam latch in the unlatched or latched position. 4. The cluster box mail delivery unit locking system of claim 3, comprising a guard assembly where the cam latch is retracted into a back side of a parcel door in the unlatched position. 5. The cluster box mail delivery unit locking system of claim 3, wherein the lock prevents the key-turnable member from re-locking. 6. The cluster box mail delivery unit locking system of claim 3, comprising spring members coupled between the operating arm and the lock controlling pivoting by the operating arm. 7. The cluster box mail delivery unit locking system of claim 1, comprising at least one additional cam latch and at least one additional strike for engaging with the at least one additional cam latch. 8. The cluster box mail delivery unit locking system of claim 7, comprising an additional linkage to position the at least one additional cam latch in an unlatched or latched position with the at least one additional strike. 9. A dual-lock system for a cluster box mail delivery unit comprising: a cam latch connectable to the closure for pivotal movement about a first pivot axis between a latched position and an unlatched position, the system including a strike for engaging with the cam latch in the latched position, and disengaging from the cam latch in the unlatched position;a key-turnable member connectable to the closure and connected to an operating arm for pivoting the operating arm relative to the closure about a second pivot axis spaced from the first pivot axis between a normal position and an operated position;a linkage coupled to the operating arm and the cam latch for pivoting the cam latch from the latched position to the unlatched position in response to pivotal movement of the operating arm from the normal position to the operated position, and for pivoting the cam latch from the unlatched position to the latched position in response to pivotal movement of the operating arm from the operated position to the normal position;a mounting member connectable to the closure for defining an externally threaded surface that extends substantially concentrically about the first pivot axis;an internally threaded passage formed through the cam latch and configured to be threaded onto the externally threaded surface of the mounting member for mounting the cam latch on the closure for pivotal movement between the latched and unlatched positions;a lock interacting with retractable-extensible latch bolts controlling the operating arm to pivot the cam latch. 10. The dual-lock system for a cluster box mail delivery unit claim 9, wherein the lock is a high security lock. 11. A multi-cam locking system for a cluster box mail delivery unit comprising: a cam latch connectable to the closure for pivotal movement about a first pivot axis between a latched position and an unlatched position, the system including a strike for engaging with the cam latch in the latched position, and disengaging from the cam latch in the unlatched position;a key-turnable member connectable to the closure and connected to an operating arm for pivoting the operating arm relative to the closure about a second pivot axis spaced from the first pivot axis between a normal position and an operated position;a linkage coupled to the operating arm and the cam latch for pivoting the cam latch from the latched position to the unlatched position in response to pivotal movement of the operating arm from the normal position to the operated position, and for pivoting the cam latch from the unlatched position to the latched position in response to pivotal movement of the operating arm from the operated position to the normal position;a mounting member connectable to the closure for defining an externally threaded surface that extends substantially concentrically about the first pivot axis;an internally threaded passage formed through the cam latch and configured to be threaded onto the externally threaded surface of the mounting member for mounting the cam latch on the closure for pivotal movement between the latched and unlatched positions;a second cam latch connectable to the closure for pivotal movement about a third pivot axis between the latched position and the unlatched position;a second strike for engaging with the second cam latch in the latched position, and disengaging from the second cam latch in the unlatched position; andan additional linkage to position the second cam latch in the unlatched or latched position with the second strike. 12.
