PeakWorks 4 ft. shock-absorbing lanyard is made with a maximum-strength, heavy-duty 1 in. polyester webbing. This superior-grade lanyard also includes a tear-away shock absorber. Shock pack is designed to tear the inner webbing to reduce the force the worker feels to an acceptable level. The lanyard also resists abrasion and harmful UV-rays and meets ANSI Z359.13 standards.
