Fortress – Ultimate Secure Mailbox


Fortress – Ultimate Secure Mailbox
From: $575.00
Ready to Stump the Thieves?
The Fortress will solve your mail theft issues. It has the same dimensions as the Large Standard but has a designated outgoing mail section and the slot is covered by a door, with a pull-down handle. The shell is made of ¼” steel and has reinforced recessed doors, a narrow slot, with an extra layer of protection from the elements with the door covering the incoming mail slot. Be prepared to be wowed.
Your Style
You double check the locks on your doors before you lie down to sleep; you love a full pantry in case of emergencies; you occasionally think through possible safety situations and how you would act in each one. Sound familiar? You’re a keeper, a defender, a watcher. You love knowing that your things and your people are safe and protected. We do too!
The Fortress Mailbox is our best-selling mailbox and is designed to be a fortress of ¼” steel protection around your mail and identity.
This is How It Works!
The mail carrier will pull down on the handle, revealing the incoming mail slot at the top (11.5” W x 1.75” H). Your incoming mail will be inserted and will drop down into the locked compartment. You are the only one with a key! Your mail awaits you, safely protected in a fortress of armor.
The Fortress also has an outgoing capacity. When the handle is pulled down, an outgoing mail shelf, (completely enclosed, and separate from the incoming area), is behind the door, below the incoming mail slot. The Fortress comes with a flag. Your outgoing mail cannot be locked by postal standards, but it’s out of sight, behind a door.
The Fortress is pre-drilled on the bottom. 4 holes, 6 ¾” apart, and designed to fit our Large Posts. It can also be mounted to existing surfaces.
It comes with our amazing, thick powder-coating finish to combat all the elements.
The Fortress is USPS Postmaster General approved.

Thank you again – I was able to ship them to Hawaii overnight, and they were installed today. We really appreciate the quality, and my thanks to your staff!

Eight years ago, I was plagued by kids pounding my mailbox with bats during baseball season. After replacing several boxes and much expense, it was time to look for a long term alternative. I found you! Of course, shortly after my new Ft Knox Box was first installed, it was tested (as evident by some wood splinters) yet came through with flying colors…and probably broke some idiot’s wrist, arm and shoulder. This weekend, though, my noble mailbox had its ultimate test: Some Einstein shot it with a shotgun!
Yes, the paint job was damaged, as were its house numbers, but that shotgun blast was no match for your 1/4″ thick steel! Thanks again for a first-rate, excellent Made in the USA product!

Called today to request “Fort Knox Mailbox” replacement stickers for our mailbox. We installed this mailbox not long after we moved into this home almost 20 years ago. It was a “developed farm” and the locals were not inclined to stop using our three wooded acres as their beer party venue. When my son and I challenged them, they responded by knocking over the original wood post mounted mailbox. At that point, we bought our Fort Knox, and have not had an issue since!
You’re awesome! Thank you!!

Hello, I just received (2) of your Fortress Boxes. These were definitely worth the wait! I am confident these will be our “forever” mailboxes. I really appreciate your company delivering premium quality and going to this level with the details. I am sometimes a difficult customer, but everything (including the packaging) was over the top. I will recommend your products whenever I have the chance. Thank you

The last box I purchased and installed got destroyed in less than a year, so I resolved to find a mailbox that could actually survive a bit of punishment. I ended up picking out The Fortress.
Some fool just hit this box hard enough to completely obliterate their entire side-view mirror assembly (glass was completely shattered and only held together by the backing, and the plastic housing was in shards all over my driveway.) The Fortress, by comparison… is missing a small section of powdercoat, and stands ramrod straight as always. *Thank you* for making exactly what I needed. –

Just wanted to say thank you for an amazing mailbox. In the picture you can see they did not get into my mailbox so again thank you and my neighbors are asking what it is so I’m sending them your way. Thanks for the quality American made product.

I wanted a mailbox that would hit back if someone tried to take a bat to it, and this certainly fits the bill!

Last month I sent you a photo of my Ft. Knox Mailbox that was ‘attacked’ by a shotgun-toting idiot. Just wanted you to know my box is repainted, re-lettered and back on post. Learned from my postal carrier that others on my highway with those big-box cast aluminum mailboxes didn’t do as well. Those owners found their mailboxes in tiny pieces…only the post remained.
The mail carrier was so impressed by your design, she has been spreading the word and so if you see a spike in sales from this area.
Best regards,
Nick T.
