The Senator — Big Security. Built for Mail and Packages
12" x 18" x 23" @ 148 LBS.
The Senator is a powerhouse mailbox: 148 pounds of heavy-duty steel, including a ¼" steel body, recessed doors, and reinforced protection for both mail and packages.
It combines the proven design of our Fortress Mailbox with a separate locking package compartment below. From checks and prescriptions to online orders, everything stays secure in one rugged unit.
Yes, it’s hefty—but it still ships by FedEx or UPS Ground.

Inspired by a Great Idea—from a Real Senator
One of our customers, a former senator, asked if we could adapt the Fortress design to include a separate package section. We loved the idea—and the Senator Mailbox was born.
Today, it’s a favorite among customers who want no-compromise security for every kind of delivery.
How It Works
The Senator has three sections:
-
Upper Section (unlocked)
- The mail carrier pulls down the handle and inserts mail into the incoming slot.
- Outgoing mail rests on a separate enclosed shelf below the incoming slot.
- It cannot be locked under postal standards, but it remains hidden behind the door.
- Includes a ¼" powder-coated steel flag.
-
Middle Section (locked)
- This is where you retrieve incoming mail.
- It stays secure and is accessible only with your key.
-
Lower Section (package compartment)
- Comes standard with a Slam Lock.
- After retrieving your packages, leave the door slightly ajar. The carrier places new packages inside and closes the door, which automatically locks.
- Holds packages up to approximately 5 ½" H x 10 ½" W x 16" D—about the size of a large shoebox.
Additional details:
- Pre-drilled on the bottom (4 holes, 6 ¾" apart) to fit our Large Posts.
- Mountable to other suitable existing surfaces.
- Finished with thick powder coating inside and out for maximum durability.
