Atlas was designed for dynamic rigging. Sterling has been engineering ropes to handle high kinetic energy loads for over two decades. This polyester sheath, nylon core construction offers a soft hand and easy knotability even on the burliest rigging jobs. This 9/16� Atlas rigging line has been completely redesigned and is now 32% stronger than our previous 9/16� model. The new core construction has lowered the static elongation but still allows rope to absorb energy/impact force and can limit peak forces when catching wood in negative rigging applications.
