Use this 46″ in-ground mailbox post to mount any curbside Mail Boss locking mailbox. The In Ground Post should be buried approximately 12″ in ground in order for the incoming mail slot of the Mail Boss mailboxes to be within USPS specifications of 41″-45″ above the road side surface. This post will fit securely over a treated wooden 4″x4″ post for deep installations and reinforcement with rebar stakes, and makes for a perfect mailbox post cover.
Post Measures: 43" H x 4.3" D x 4.0" W
