The Gibbs #4 Rope Clamp is designed for ropes with diameters from 5/8" - 3/4". It is crafted from aluminum or stainless steel and has a quick-release cam so it can be installed anywhere on the rope or lanyard. Adjustable lanyard clamps are mainly used in hauling systems and to build adjustable lanyards. Cam-loaded clamps apply the load directly to the cam so that they will engage even if the rope is muddy, wet, or icy.
