Extra-Grip Wet-Environment Grip-Tight Rope—Not for Lifting

A coarse, natural texture makes this rope easier to grip than other wet-environment rope. Rope floats in water, resists rot, and doesn’t lose strength when wet. It also resists acid, oil, and gas, and knots easily.

Note: The safety factor for capacity is 12:1.
