M1-LT Steel Post

2.5″ x 2.5″ x 57″ Matching Steel Post for the M1-LT Mailbox.

The M1-LT Steel Post specifically supports the M1-LT Mailbox. It’s a 10 gauge square steel post with a welded 6.5″ square 3/16″ steel plate, with pre-drilled holes to match with the mailbox holes for easy installation. Fort Knox Mailboxes can be mounted to almost any type of post that is made out of most structural materials. Our mailboxes come with four holes drilled in the bottom of the mailbox for easy mounting to multiple surfaces. We recommend whatever you are mounting a Fort Knox Mailbox to, is substantial and can handle the weight of the mailbox. You also want it mounted in a way that keeps the mailbox from being stolen. If what you have is not going to support your new mailbox, then we have a matching 57″ long steel post for a quick and easy installation. It installs like a fence post in the ground, and needs to be approximately 2 feet down in the ground and cemented in. We suggest one or two bags of cement. If you need a post to be surface mounted to a sidewalk or cement slab, we also have surface mount posts (Breakaway).

(Mailbox Sold Separately)

Available Options:

– In-Ground Post for cementing in a dirt area

– Surface Mount (Break-Away) for bolting to cement (+$25)

The steel posts that we use to support the M1-LT Mailbox:

The post comes separate from the mailbox and is bolted from underneath with carriage bolts. This is ideal if you move and want to take the mailbox with you instead of pulling the steel post out of the concrete. Posts are made of 10 gauge square tubing (10 gauge = 1/8″). The posts are buried in approximately 2 feet of concrete.
