Having problems with theft? Our patented SmartLock system could be the answer. With SmartLock, you close the door to your mailbox and lock it. The door can now be opened just once more without a key, so your postal carrier doesn't need a key to open the door and deposit your mail. But once the door is shut again, only a key will gain you access. SmartLock is a simple but very effective way to protect your mail, and at a time when identity theft is the fastest growing white collar crime in America, that's important! The Lexington style mailbox is available in both basic and brass upgrade models in the following colors: white, black, green, burgundy, desert sand, and bronze.SmartLock detail (mailbox shown in green and with optional medallion)" Made with extra thick high strength steel plate" Heavy cast aluminum door " Total weight is 42 lbs." 9.5" wide x 12.5" high x 22" deep" Limited lifetime warranty" Durable 3-stage baked powder coat finish" Heavy steel flag with stainless steel fasteners or" Optional brass upgrade includes medallion and flag" Mounts with or without additional bracket to all Mailbox Posts.
