Do you love a ‘one and done’ purchase?
If you’re the kind of person who loves a long-term solution, we understand! We do too! Who wants to replace a mailbox every few years, or months? Fort Knox Mailboxes are designed to be standing outside your home for DECADES after purchase. They really do last that long, and we have tens of thousands of customers who can testify to this. Fort Knox Mailboxes have been around since 1994, and they’re still standing strong.

They can withstand extreme situations
We do love to hear customers’ stories, and over the years, we’ve heard a lot! Here are some things that Fort Knox Mailboxes withstand:
- Baseball Bats – We love to say that we’ve been “breaking bats since 1994.” Seriously, a baseball bat is no match for our ¼” steel shells. Anyone who hits one with a baseball bat will have serious regrets.
- Sledge Hammers – Our mailboxes can really take a beating.
- Vehicles – We’ve certainly heard of many vehicles hitting our mailboxes over the years. The mailbox always wins! Most customers can simply re-install the mailbox. The mailbox usually suffers some scratches, and at most, a post might need replacing. But the mailbox always does the job.
- Snow Plows – Heavy plows can occasionally hit our mailboxes, but you’re not going to have to worry about the Fort Knox Mailbox withstanding.
- Mailbox Bombs and Fire Crackers – We’ve heard it all! Think of the Fort Knox Mailbox as many pounds of steel armor.
Indestructible quality
A Fort Knox Mailbox is an unbreakable stronghold. We start with ¼” steel, which is the same steel used to build skyscrapers. Each mailbox is all welded, with no rivets, no weak spots. Our high-performance powder coating is a great protective finish, designed to withstand the weather. This means your Fort Knox Mailbox will not only be incredibly tough and enduring, but it will also be looking sharp outside your house.
