This TWXpert® Shock Absorbing Lanyard is a specific type of safety lanyard used in conjunction with safety harnesses as a part of a fall protection system. Generally, shock absorbing lanyards are used when working at a height of more than six feet above the ground. The unique feature of a shock absorbing lanyard is that it has a built-in woven inner core that expands during the fall to ensure that the fall arrest force is significantly reduced
