The PeakWorks SA-54022-4 is a 4' (1.2M) twin-leg lanyard fitted with snap and form hooks. Its SP shock absorber uses woven tear webbing that separates under load, absorbing downward force to help reduce injury. Positioned beside the body connector, the folded webbing sits inside a sewn-in, shrink-wrapped pack. The SP range includes different construction and worker-weight categories, with the range specifications outlined below.
