Introduction

The maximum security locking mailbox that started it all. The Fort Knox large standard is almost 100 pounds of solid steel (96 to be exact) tough enough to stop even the most determined mail thief.

This product page is for the large standard which will hold 2 weeks of mail. If don't need that much space have a look at the small standard here which will give you 1 weeks worth of mail storage. 

Both the Fort Knox small standard and large standard mailboxes are built to the same specifications.

If mail security is your number one priority when choosing a mailbox. Look no further than the famous Fort Knox Mailboxes - commonly referred to as a safe mounted on a post! 

Our Fort Knox Large Standard mailbox has an anti-fishing measure with nearly 6 inches of metal extension shelf at the incoming mail slot so if someone were to try and put a “fishing line” down into the box to grab the mail, the mail would catch on the extension shelf, drop back down, and would not come out of the incoming mail slot.
