The 1600 series front-loading horizontal mailboxes were developed for use in large private installations not serviced by the USPS like military bases, colleges, universities, and office buildings.
This unit includes 20 secure front-loading individual mailboxes. The compartment size is smaller than USPS regulations, but is convenient when working with limited wall space, as more of these secure mailboxes fit into each module. The private distribution 1600 series commercial mailboxes do meet all other regulations.
Each tenant door measures 4"W x 5"H with a 5-pin cam lock, two keys, and a clear plastic 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. However this door can still be used as an outgoing mail slot or office dropbox upon request.
