Fort Knox Mailbox Construction

So we have your curiosity on how our mailboxes are made? Most of our mailboxes are constructed from the same 1/4″ thick steel unless specified. Each 1/4″ thick mailbox has 3/16″ reinforced locking steel doors and are individually hand made here in the USA. We manufacture the strongest, most secure locking mailboxes on the market by far!
We don’t just make secure mailboxes.
We make HIGH SECURITY mailboxes!
Below will show you why we are NOT
your average locking mailbox.

Fort Knox Mailbox Features

Scroll over the image areas that have a light grey outline around them or select features for details on the construction of our mailboxes. Click outside of a feature to deselect it.

Current selectable locations include:

  • Steel Flag
  • Top Door (unlocked)
  • Address Numbers
  • Middle Lock
  • Middle Hinge
  • Bottom Lock
  • Bottom Door
  • Just under the mailbox

Want to know about the 1/4" steel we use?

The reason why we are HIGH SECURITY is that the steel we use to produce the strongest mailboxes in the world, is also used to construct some of the largest bridges and skyscrapers in the world. The 1/4″ steel will withstand bats, rocks, sledgehammers, and yes…even those dreaded mailbox bombs.

We can also mention that they do pretty good against VEHICLES! These mailboxes have been lab tested against other “high security” mailboxes with many types of destruction and only the Fort Knox Mailbox passed with flying colors.  A 28 ton boom truck and trailer came out on the minus side after hitting one of our mailboxes.

If you ever have a chance to pick one up and feel their heavy weight, you will understand why these mailboxes are so tough. The weight of our mailboxes alone will amaze you. For example:

THE STEEL POSTS THAT WE USE TO SUPPORT OUR HEAVY MAILBOXES

M1-LT mailbox: 2.5″ x 2.5″ x 57″ long
Small standard mailbox: 4″ x 4″ x 57″ long
larger mailboxes: 5″ x 5″ x 57″ long

If you have a preexisting post, make sure it can support the above mailbox weight

4" X 4" AND 5" X 5" STEEL POSTS

The post comes separate from the mailbox and is bolted from underneath with “carriage bolts,” so that no theft of the mailbox is possible. This is also 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 10 gauge square tubing. (10 gauge = 1/8″). The posts are buried in 2+ feet of concrete.

CUSTOM POSTS & RACKS

WELDING VS. RIVETS

NO COMPARISON!

weldgif2

Both are good in construction of certain products, but for long lasting durability and security, welded is the best choice for a mailbox. ALL Fort Knox Mailboxes are personally hand welded with no rivets needed. A welded mailbox, as opposed to rivets, increases the durability and security tremendously. Thieves are often able to pull the riveted sides off other mailboxes and get to your mail with hardly any effort at all. Not so with a Fort Knox Mailbox. You can see in the picture to the right where the 3/16″ back plate has been completely welded. It just doesn’t get any stronger than this!

Two words sum it up and those are, durability and security.

Available option: Front and rear access doors
If you need to retrieve your mailbox from the rear of the mailbox, we can make that possible. This is made for those who live on a busy street, or would like to put their mailbox through a fence or masonry and retrieve mail from the back of the mailbox instead of the front.

There is a $68 charge for this rear door option, and you get 3 additional options:

  1. Front and rear doors “keyed alike” (upgraded locks require additional purchase).
  2. Front door is made “fake” (front door is welded shut from the inside with fake lock).
  3. Front locked door is replaced with a “solid plate” completely welded.

ALL STEEL MATERIALS WITH A BAKED-ON "POWDER COATED" FINISH

PowderCoatTough

Protective and/or decorative coatings are formed by application of powder to a substrate, after which the powder is fused into a continuous film by the application or heat or radiant energy. Powder coating is an advanced method of applying a decorative and protective finish to a wide range of materials and products that are used by both industries and consumers.

The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven. The result is a uniform, durable, high quality, and attractive finish.

THE FORT KNOX LOCKS

7 Pin Tumbler Locks (Round Keyed)

These locks come standard with the Fort Knox Mailbox.

They are a chrome plated “tubular” 7 pin key lock. Tubular locks are more durable (pick-proof) than the common keyed lock. The cams that hold the Fort Knox Mailbox doors shut are 1/8″ steel which is thick enough to keep out unwanted criminals.

2 keys included with lock.

Slam Lock

This lock is designed for those who frequently get packages larger than the 1-3/4″ slot.

It is made so that you can leave the main door unlocked to receive packages. The mail carrier opens the slam lock door, takes the outgoing mail, places your mail and package in the mailbox, and shuts the Slam Lock door, automatically locking it. *One Year Warranty*

2 keys included with the lock

Abloy Cl Series
“Double D” Hole Cam Lock

This is the most reliable security lock available for coin-operated laundry equipment, vending machines, coin boxes, slot machines, music, and gambling machines, payphones and other high-security applications.

And now…FORT KNOX MAILBOXES!

2 keys included with lock

Medeco Cam Lock

The Medeco3 unique design provides triple locking action, making the locks virtually pick proof.

All Medeco keys and locks are protected under patent, trademark, and copyright laws. Medeco3 keys may only be duplicated by Medeco or by a Medeco authorized sales outlet, and only at your request.

2 keys included with lock

The Vault Lock

For people who want above and beyond security.

This lock works just as our standard and Abloy locks, but with added strength. It works like a safe or vault lock mechanism where when locked, two 1/2″ steel pins along with our 1/8″ thick cam slide into a locked position. It is used when extreme security is needed.

The Vault Lock Extreme

Do you need even more security? Same great benefits as the Vault Lock, but with the upgraded Medeco lock to give your mailbox the best-offered security possible.

Forget high security, this is EXTREME security!
