Vault Series – Anti Theft Mailbox
Vault Series – Anti Theft Mailbox
From: $1,800.00
100% Fuss Free & a Fan Favorite
The Vault Series of mailboxes are a customer favorite. This is the ULTIMATE mailbox, in both function and security. They are made from our ¼” steel, with recessed doors, all hand welded, and no pry points. In addition, the Vaults have a baffle up top, completely closing off all entry points for fishing attempts. All Vaults automatically include our Vault Lock. This includes two steel pins behind the door, as well as a lock in the front. They’re double-locked, always. The Vaults are fabricated to withstand the absolute toughest circumstances! This is why we call them THE VAULTS.
This superior mailbox can be installed for either residential or commercial use and you’ll never worry or fret over your mail and packages again. It will be standing for decades to come.
There are 4 different sizes available, depending on your needs. Want a custom size, just let us know (custom@fortknoxmailbox.com).
Ideal for the Traveler
The Vault differs from our other mailboxes because it has the baffle system up top, instead of a mail slot. Check out the cut-a-way diagram below! The Vault will accept packages and mail in the main compartment, with no need to re-open a Slam Lock door each day. You do not need to check your mail regularly. The Vaults have lots of storage space and will hold all your items safely until you return home.
This is How It Works!
The mail carrier will pull down on the handle, place your mail and packages inside the baffle door. As the mail carrier closes the door, the mail and packages fall into the locked compartment. You are the only one with a key!
There are 4 different sizes of Vaults available:
- Vault (12” W x 24” H x 23” D ; 170 lbs)
$1,800- Accepts a 3” tall package
- Vault XL (12” W x 36” H x 24” D ; 225 lbs)
