The M1-LT mailbox is made of heavy-duty 1/8″ thick steel (11 gauge).  Half as thick as our other mailboxes, but it can still take a beating.  The M1-LT is thicker than any other locking mailbox on the market and designed for those needing a high security option without the extreme weight.  The M1-LT can hold an average of one week of mail.  Included are two high-security tubular keys for the 7 pin tubular lock (which is upgradable), and free address numbers.  Why purchase the M1-LT? It’s strong,  built like a small “tank”, and ready to defend your mail!
