The 1450 & 1550 Series Horizontal Mailboxes are developed for use in large private institutions not serviced by the USPS such as military bases, colleges, universities, and hotels. These 47-door mailbox units meet all USPS regulations except those pertaining to compartment size. The smaller mailbox compartments allow for more mailboxes per module, and are useful in areas with limited wall space.
Each door of this system features a 5-pin cam lock with two keys and a clear plastic window number slot for tenant identification. Please note that one mailbox door will be used as a master door and cannot be used as a tenant door. Howver, this door can still be used as an outgoing mail slot or as an office drop box, upon request.
