Type 30N-X-54 high deflection spring hangers provide far greater vibration control than the lower deflection rubber hangers. 30N hangers are used to isolate noise and vibration from ceiling suspended equipment being hung from threaded rod. The lower rod has the ability to swing up to 30 degrees for ease in installation to compensate for misalignment. Spring and LDS rubber element in conjunction remove high and low frequency noise. Each individual hanger handles a weight capacity of 54 lbs.
