Protect 4x4 Wood Posts from Ground-Line Rot The RotGuard™ 4x4 Series is a pre-sized, self-adhesive wood post wrap engineered to protect 4x4 fence posts, deck posts, mailbox posts, and structural wood posts from ground-line rot. Designed to fit square or round posts up to 4.125”, this 16-inch wrap delivers targeted soil-line protection where moisture exposure and fungal decay most commonly occur. Ships next business day from Pennsylvania (U.S.) or Ontario (Canada). Apply before installation to extend post life and reduce costly post replacement. Product Overview | Wood posts rarely fail above grade. They fail at the soil line, the critical zone where moisture, oxygen, and soil organisms combine to create decay. Even pressure-treated lumber can deteriorate over time when exposed to constant ground moisture. RotGuard™ forms a durable waterproof barrier at the critical soil-line zone, helping reduce moisture intrusion and fungal decay at the most common post failure point. RotGuard™ wrap
