We've improved the already high visibility of the Technora and polyester sheath on our RIT Line by adding a strand of highly reflective 3M tape. The 100% Technora core provides high strength in adverse conditions. The line is supple enough to pack easily, but firm enough to feel against the floor when following it in low-visibility conditions when wearing gloves. Technora chars at 900F (482 C). Polyester melts at 480F (249C). Rope is sold by the foot. Please contact Dynamic Rescue Customer Support for maximum length available.
