Vibro-WS Anti-vibration Supports is a specially designed homogeneous rubber support systems for gypsum board partitions. The semi-cylindrical modulation at their base (for WS.75 & 100) and the transversal holes (for WS.50), provides the necessary space for the rubber expansion to increase the deflection and consequently the vibration insulation. The inclined flaps of Vibro-WS cover the fixing bolts on the base and prevent possible contact with gypsum board.
