GREAT MAILBOX!!
this is a great mailbox! USPS approved! i got my mail stolen many times before i got this mailbox. after this purchase, all my mails are safe and sound. USPS also submitted a work order to get the master USPS lock installed. the installation portion sucked BUT.. this item is great. overall this is a great item. highly recommended!!

Not useable, lock system out of date
The Post Office in Worcester, MA would not install their master lock (for the mailman to open the box) because it must be version USPS-STD-4C, the box i received is USPS-STD-4B+, an older problematic version. So, I now own a 3 gang mailbox that is not useable. The manufacturer, Salisbury Industries, would not help me by doing an exchange.
