Don't settle for less when you can get the best dock box on the market sold to World Class Marinas from New York to Singapore.

Unlike boats, dock boxes should not be made of fiberglass. Fiberglass needs waxing or it will chalk, spider web crack and retain dirt. On impact, fiberglass will crack and deform. Trionic extra heavy-duty dock boxes are rotationally cast in a mold with impact-resistant polyethylene resin. The smooth exterior surface repels dirt without waxing. Over 30 years of experience in the marine industry.
