Give your old, weathered mailbox post a fresh, clean look with this maintenance-free vinyl sleeve. It's designed to slide right over an existing (or new) standard wood 4x4 post (actual size 3.5\x3.5\). The cross-arm is 26 inches wide to hold two mailboxes (mailboxes NOT included), and the total height from the ground to the bottom of the cross-arm is 42 inches. Made from durable PVC vinyl that won't rot, peel, or need painting, and it comes with a lifetime warranty. Includes stainless steel hardware for securing your mailboxes to it. A simple, cost-effective way to upgrade your curb appeal without replacing the whole post structure.
