The USPS Series - 4C Horizontal Max Security Mailboxes are Structurally Engineered for Security, Durability and Clean Elegant Lines

These High Security Commercial Mailboxes are expertly crafted, with solid aluminum blocks reinforcing each corner of the outer frame. One inch thick solid aluminum angle bars inside every corner of the master loading door prevent sagging, tilting, or door shifting – eliminating jamming issues common in less robust systems. Additionally, horizontally extruded 3/4 inch ribs at the top and bottom of each tenant door provide unparalleled strength against bending or prying to thwart vandals and thieves.

Flush mounted self-closing flaps, and the elimination of bolt heads around the arrow lock and hinges allows the true anodized finish to shine through in your lobby or courtyard. Double aluminum panels within the parcel doors conceal hardware and locking mechanisms while seamlessly incorporating C channels for added reinforcement. Quick-fix connectors allow for stacking column mailboxes directly onto the parcel locker cabinet.
