Mailboss Post Steel

The Mail Boss steel post is built to carry a Mail Boss locking curbside mailbox. Choose an in-ground post to set in concrete, or a mounting or surface mount post to bolt onto an existing concrete pad with a base plate. Heavy gauge galvanized steel and a powder coat finish keep it solid.

• Pre-threaded holes accept 8 mm x 1.25 coarse bolts; 4 mounting bolts included.
• Every post fits the Mail Boss surface mount base plate (sold separately).
• Colors: Black, Bronze, Granite, White, Alpine White and Wood Grain (varies by post).

Installation

The in-ground post is usually buried about a foot deep and set in concrete. For a deeper install it can fit over a treated 4 x 4 post. The 37 in and 27 in posts bolt to a steel base plate that is anchored to concrete. Read our curbside mailbox installation guide and the post guides on our installation guides page. Check with your local postmaster before installing, since local rules on mailbox type and placement can vary.

Frequently asked questions

Which post do I need?

Use the 43 in In-Ground post (or the 46 in stainless version) to set the post in soil with concrete. Use the 37 in Mounting Post or 27 in Surface Mount Post to bolt onto an existing concrete surface with a base plate. Check with your local postmaster before installing, since local rules on mailbox type and placement can vary.

Is the base plate included?

No. The 37 in and 27 in posts need the surface mount base plate, sold separately. Each post includes 4 mounting bolts and instructions.

Will it fit a mailbox that is not a Mail Boss?

It is designed for Mail Boss curbside locking mailboxes. The top holes are pre-threaded for 8 mm x 1.25 coarse bolts; check the hole pattern drawing below against your mailbox before ordering.

How high should my mailbox be?

Our installation guide follows USPS guidance: the mail slot 41 to 45 in above the road and the front of the box 6 to 8 in back from the curb. For more height on the in-ground post, it can be set over a treated 4 x 4 post.

Is there a stainless steel post?

Yes. The In-Ground (46 in) post is made of 316 stainless steel.

Is there a warranty?

Yes. Mail Boss products carry a limited lifetime warranty from Epoch Design for the original owner, covering manufacturing defects under normal residential use.
