Instead of a flimsy tin box, this is a heavy-duty fortress made from 14- and 16-gauge galvanized welded steel designed to withstand vandalism. What really sets it apart is the innovative baffle door system. It allows you to drop in small parcels and checks without giving thieves a way to fish your mail out. The security is serious, too, featuring a patented anti-pry latch and a 12-disc wafer lock that resists drilling and picking. It is a robust, USPS-approved solution for anyone tired of worrying about identity theft or stolen packages sitting at the end of the driveway.

Most people assume a mailbox is just a metal box on a stick, but the Arlington model treats it more like a piece of curb appeal architecture.
