The Vault : Large 1/4 Inch Steel High Security Parcel Locker
The Vault — Built Like a Vault—Because It Is One
12" x 24" x 23" @ 170 LBS.
Think bank-vault security—for your mail and packages. With the Vault, you can trust that your deliveries are protected.
This is the smallest model in the Vault Series, but don’t let its size fool you. It’s built to the same standard as every Vault: ¼" solid-steel construction, hand-welded seams, an incoming-mail baffle, reinforced recessed doors, and virtually no exposed pry points.
What Makes It Different
The Vault features a fully enclosed baffle system on top—no exposed mail slot and no easy path for fishing mail back out.
Every Vault comes standard with the Vault Lock Extreme:
- Two ⅜"-thick internal steel locking pins
- Three-point locking mechanism that secures the door in three locations
- Includes a Medeco® lock with 2 keys
Built for both residential and commercial use, this is serious all-steel protection made to last for decades.

- Available in four sizes
- Stores large volumes of mail and packages in one secure compartment

How It Works
Simple. Secure. Built Like a Tank.
- The carrier pulls down the handle, raising the protected baffle inside.
- The carrier inserts mail and packages into the baffled delivery area.
- As the door closes, the deliveries fall into the locked compartment below.
- Only you have the key—providing peace of mind every day.
- Add the optional ¼"-thick outgoing-mail flag. Outgoing mail is stored inside the upper portion of the mailbox in a 1½"-tall section that accommodates multiple envelope sizes.
