4C Horizontal Depot Mailboxes

While most 4C horizontal mailboxes are recessed into a wall, a 4C depot mailbox offers a flexible, freestanding solution. Ideal for large mailrooms, military bases, or universities where wall space is limited or a non-permanent installation is desired, these units provide all the security and compliance of a standard 4C system without the need for construction.
