Salsbury Maximum Height Surface Mounted 4C Horizontal Mailbox | 29 Doors with Private Access

The Salsbury 3816D-29AFP is a 4C surface mounted horizontal mailbox unit from the 3800 Series, designed for colleges, schools, private postal centers, corporate mail centers, military bases, government agencies, and other applications requiring maximum-density private mail delivery infrastructure in locations where walls are not deep enough for a recessed installation. This double-column, maximum height unit combines a 4C horizontal mailbox module with a matching surface mounted enclosure and master commercial locks, housing twenty-nine tenant compartments within a single self-contained structure requiring only minor assembly, making it one of the highest tenant-capacity configurations available in the 3800 Series surface mounted line. Front-loading access through easy-opening master door panels and private access configuration make this unit well suited for controlled environments where USPS carrier access is not required.
