4 Single Height Tenant Doors Front Loading Flex-S4 USPS Approved 4C Horizontal Mailboxes

2B Global brings exceptional quality to their line of USPS 4C Mailboxes. Engineered from a combination of steel and aluminum, these mailboxes have reinforced corners, horizontal bars, and vertical trims that provide proven tensile strength. Solid aluminum blocks in the master loading doors keep them from sagging or distorting. Both the tenant and master doors are reinforced with a 1" thick angle bar inside each corner, then braced with extruded 3/4" ribs, increasing the binding strength and thus, resistance. A multi-point eyelet latch automatically locks when the door swings closed ensuring security while protecting postal carriers from sharp protrusions. Designed to deter theft while functioning effortlessly, 2B Global's 4Cs feature flush-mounted self-closing mail flaps, hidden bolt heads and a smooth anodized finish in a variety of colors. Door plates come in your choice of aluminum number plates or black-filled engraved numbers.
