Break-Away / Surface Mount

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. They are especially easily mounted to our posts. With two styles to choose from, this surface mount option is made for mounting on an existing cement slab or sidewalk. Unlike our other in-ground post, this post is made for above the surface. Depending upon what size of mailbox you have, will determine the length of the post you need to reach the proper USPS height requirement. Let us know if this is to be mounted on a curb or surface mounted so we can give you the closest required height possible.

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 11 gauge square tubing (11 gauge = 1/8″) with 3/16″ steel plates.

Hardware is included for mounting the mailbox to the steel post, but not included for mounting to the sidewalk or cement slab due to many different types of hardware available. Talk to your local hardware store to see what is the recommended type of hardware for your installation.
