Safety Blue climbing rope; an industry favorite for years. These tightly plied, polyester 16-strand lines from Safety Blue offer a smooth, snag-resistant surface. Polyolefin yarns in the core of each cover strand reduce weight and improve handling. Twisted parallel blue yarns, in a trademark blue core, allow the rope to stay firm and round while in use. The core also acts as a warning flag if the cover is ever cut. The tough, durable cover is treated w a protective finish that minimizes abrasion and maximizes rope life. Safety Blue's lack of dye gives it a higher tensile strength than High-Vee. Try Safety Blue climbing rope today! Tensile Strength 7,000 lbs. (31 kN) Elongation 4.5% at 540 lbs.
