Heavy-duty with durable cypress top and galvanized steel tubing. Our natural Carolina cypress lasts for years even under wet conditions. The dressed, wooden box has smooth, spinter-free surfaces and the corners are re-inforced with metal plates. The steel pipe framework easily supports the box, even filled with wet medium. Pipe and fittings are galvanized for a long, rust-free life. The box section is 2 feet 6 inches wide, 5 inches deep (inside) and is available in two lengths: 3 feet or 6 feet. Bench height is 2 feet 8 inches. The box section comes fully assembled. The support section assembles easily with one hand tool.
