The 1450 & 1550 series horizontal mailboxes were developed for large private institutions not serviced by the USPS, including military bases, colleges, universities, and hotels. This 54-door mailbox system is constructed of heavy-gauge aluminum and meets all USPS regulations except those pertaining to compartment size. The smaller compartments allow for more mailboxes per module, and are useful in areas with limited wall space.
Each individual tenant door features a 5-pin cam lock with two keys and a clear plastic window number slot for tenant identification. Please note that one door will be used as a master door and cannot be used as a tenant door. This door can, however, be used as an outgoing mail slot or as an office drop box, upon request.
