Reduce the risk of theft with the highest security mailbox on the market! This 5-Door 4C Horizontal Mailbox system features five double walled tenant doors. Each unit also includes an outgoing mail slot with a sawtooth guard that prevents mail from being fished out and a smaller Carrier Access Door provides smaller pry points to increase overall strength.

Made from a high strength, stainless steel, the USPS approved 4C Horizontal mailboxes were designed with an utmost regard for security and perfection. A secure double-wall door design increases each door's pull test capacity to 1500 pounds of pressure. The flush surface design and concealed hinges make it close to impossible to tamper with and pry open these mailbox unit doors.
