This four-panel PVC column wrap with bead-and-groove joining system interlocks to avoid pounding the boards’ surface during installation. The durable panel system can be installed by one person, says the firm, and provides a smooth finished exterior. The wrap fits 4-inch-by-4-inch, 6-inch-by-6-inch, and 8-inch-by-8-inch posts, and comes in 10-foot lengths. Its white matte finish can be painted.
