VMC Group JSQ Series Wire Rope Isolators are made of captive, flexible wire rope elements with upper and lower attachment plates. The stranded-wire rope elements provide a high degree of damping with measurable, predictable vibration isolation performance. 

JSQ Square Wire Rope Isolators consist of stainless steel and are connected to zinc-plated, low carbon steel mounting discs. The isolators offer three-plane, all-axes isolation that permits use in any attitude - vertically, horizontally and laterally. The isolators offer excellent shock attenuation with low frequency, high vibration isolation damping in a dynamic environment.
