CMC Static-Pro rope is an amazingly resistant rope to both water and acids. A great choice for high lines, long rappels and other systems where rope stretch can be an issue. Less than 2% rope stretch is experienced at 300 lbf and there is no loss of strength when the rope gets wet. Knotable, single color and made of low-stretch 100% high-tenacity polyester fiber, the CMC Static-Pro lifeline is a solid piece of rope. This line is sold by the foot.
