Unmatched Durability & Vandal-Proof Features
Fort Knox Mailboxes can withstand anything life throws at them. Here’s how:
Built with 1/4″ Structural Steel
We offer solid mailboxes of 1/4″ structural steel—the same material used in skyscrapers and bridges. This makes them incredibly tough against impacts. Whether blunt force or weather extremes, our indestructible mailboxes handle it all without a dent.
Resistant to Extreme Impacts
Our mailboxes resist vandalism attempts and stand strong against bats, vehicles, and other harsh tools of destruction. This means no costly repairs or replacements down the line.
Recessed Doors & Welded Design
Recessed doors and all-welded construction add another layer of defense. These features eliminate weak points, making our mailboxes nearly impossible to breach.


Advanced Locking Systems & Customizable Options
Our advanced locking systems and customizable options take security and convenience to the next level:
High-Security Locks
Each locking mailbox comes with a standard 7-pin tubular lock. However, you can upgrade to options like the Medeco lock or the Slam lock for unrivaled security.
Multi-Mailbox Solutions for Flexibility
Fort Knox Mailbox offers solutions for multiple mailboxes on a shared steel post or rack. Perfect for larger properties or shared spaces, this option streamlines delivery security without compromising strength or performance.
Fully Customizable to Fit Your Needs
From adding an address number, flag, or motion light to other practical features, you can tailor your mailbox to perfectly fit your property’s style and needs.
