The Mail Boss is a heavy-gauge steel curbside mailbox that locks your mail away from thieves. Mail drops through a slot sized for letters and a box of checks, and only your key opens the retrieval door. It is a good fit for homeowners who want a secure, USPS-approved curbside box at a lower price than the Package Master.

- Holds about 1 to 2 weeks of mail
- Commercial-grade high-security wafer lock with 3 keys; patented anti-pry latch
