This over-the-rail utility toolbox is perfect for someone who needs something to organize their tools and other equipment. It is constructed of durable, yet lightweight ABS plastic polyethylene that will not rust or dent. It features UV protection to ensure it won't fade or deteriorate. The polyethylene is not affected by spills, including oil, gasoline and most solvents. Spring assisted lids make it easy to open. Used, but in good condition.
