We are here to answer any questions you may have. THE TRAP from Fathoms Plus has been a major scientific innovation in shellfish trap design. Years of intensive research and devlopment have produced the most efficient model to date. No nailing, scraping or dipping required. THE TRAP is constructed of high density, high impact polyethylene, making it virtually maintenance-free. It cant rust, wil not rot, resists marine growth, and will withstand the stress and strain of many highly productive seasons.
