The 1600 series horizontal mailbox system is ideal for use in large, private installations not serviced by the USPS, including colleges, military bases, and office buildings.
The smaller compartment size does not meet USPS regulations, but is convenient when wall space is limited since more mailboxes can fit into each module. The private distribution, front-loading high-security mailboxes do meet all other USPS regulations.
All tenant compartments measure 4" x 5" and feature 5-pin cam lock, two keys, and a plastic number slot for tenant identification. Please note that one door will be used as a master door and therefore cannot be used as a tenant door, However, this door can still be used as an outgoing mail slot or office dropbox upon request.
