The cable is made out of a robust braided steel wire coated with a high visibility yellow rubber. The part that connects the lanyard to the line is a generously sized stainless steel carabiner. The lanyard is fixed to the wrist through a soft bracelet with a tear-off strap. On the pulley, there is a stainless steel D-ring that can be used to hook the carabiner when the lanyard is not tied to the line. This lanyard is also equipped with a specific swivel to prevent binding of the wire. The steel wire is 100 cm/ 39” long. The carabiner can be hooked to lines of a maximum diameter of 20 mm / ¾”.
