ABSTRACT:
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 interlining 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.
