The Bunker — Rugged Mail Protection

Formerly known as the M1-LT Mailbox.

We originally named it after the Abrams tank because our mailboxes are truly “built like a tank!” However, most people aren’t familiar with that military vehicle, so we wanted a name that instantly communicates strength and protection.

That’s how The Bunker was born. Just as soldiers relied on bunkers in battle for safety and security, this mailbox is designed to give you peace of mind. Rugged, resilient, and ready for anything—it’s built to protect your mail like it’s under heavy guard.

How It Works

1. The mail carrier inserts incoming mail into the slot at the top (10” W x 1.75” H).

2. Mail drops into the always-locked compartment.

3. Only you have the key—your mail waits safely inside until you retrieve it.

The Bunker is pre-drilled on the bottom (4 holes, 4 ⅝” apart) designed to fit our Bunker Posts, but can also be installed on wood, metal, or masonry surfaces.

Outgoing Mail (Optional)

• This is a “Limited Service” mailbox, designed for incoming mail only.
• Outgoing mail option available (adds a flag and slot beneath incoming slot).
• Holds 1–4 envelopes.
