An extremely low-stretch kernmantle rescue lifeline constructed of 100% high-tenacity polyester fiber. The polyester fibers do not absorb water, so there is no loss of strength or increase in weight if the rope gets wet. With less than 2% stretch at 300 lbf, Static-Pro is an excellent choice for high lines, long rappels, and many mechanical advantage haul systems. Polyester fiber ropes have better resistance to acids than nylon, which makes Static-Pro the preferred choice in acidic environments. Favored for its excellent hand, knotability and UV resistance, Static-Pro Lifelines come in solid colors with a single stripe to prevent confusion with CMC Lifeline and other solid color kernmantle ropes. *Rope is sold by the foot. Please contact customer support for maximum length available.
