Made of heavy duty aluminum, Salsbury 4C horizontal mailbox enclosures are designed to easily mount Salsbury 3700 series front loading 4C standard and custom horizontal mailboxes. Surface mounted enclosures attach to walls for a surface mounted installation while free-standing enclosures mount to the ground and are ideal when space is limited. Both are designed for indoor and outdoor use. 4C horizontal mailboxes attach to the fully assembled enclosures with mounting hardware (included).
