Mail Boss In Ground Post - 43"



This 43 inch in-ground post can be used to mount any Mail Boss locking mailbox. It needs to be buried at 12" deep so that the mail slot of the mailboxes is above the road-side level (USPS specs of 41"- 45")

The post can safely fit over a standard 4x4 wooden post when in need of deeper installations and it has solid reinforcement with rebar.
