The Classic mailbox and post kit keeps mail time easy and your curb looking sharp. Made from tough, rust-proof, double-wall plastic, this plastic mailbox is built to handle weather, sunlight, and busy delivery days without fading or cracking. Perfectly sized, this medium mailbox has plenty of room for letters, magazines, and small packages. With dual access doors, you can grab your mail from the front or back, so you can avoid tiptoeing into traffic. This easy-to-assemble mailbox with post slides right over a wooden 4x4 post for a quick, no-fuss setup. For residential mailboxes that need equal parts function and style, the Classic mailbox kit delivers on both fronts.
