The Fortress is ready for battle! Made with a 1/4″ thick steel shell and 3/16″ thick reinforced steel doors. Weighing at just under 100 LBS., this mailbox is ready for just about anything thrown it’s way. With the same mail storage as the Large Standard, (average of 2 weeks) the Fortress is set up for outgoing mail. Behind the upper 3/16″ thick steel door is an incoming mail slot and outgoing mail compartment. Included is two high security tubular keys for the 7 pin tubular lock, all included hardware including a satin chrome handle. Last but not least is a powder coated 1/4″ steel flag.
