Step2 Town-to-Town XL Post-Mount Mailbox upgrades curb appeal and reduces mailbox trips. With an extra-large USPS T4 interior that organizes letters, magazines, padded mailers, and many small packages, deliveries stay tidy and secure. A smooth-hinged door with a magnetic closure helps keep contents dry and protected through rain, sleet, snow, and sun. The durable double-wall plastic body resists dents and rust, and the molded-in color maintains a like-new look over time. Installation is straightforward on most standard mail posts (sold separately), providing a fast, reliable mailbox upgrade for everyday residential use. Assembled dimensions: 14" H x 17" W x 20" D. Color: Onyx Black.
