This Anti Static Fixed Castor with electro conductive 125mm diameter polyurethane wheels is ideal for spark free environments such as clean rooms, laboratories and areas with highly sensitive equipment. This fixed castor can carry up to 200kg each castor so is suitable in heavy duty environments aswell. The electro conductive wheels oppose the flow of electric current improving the resistivity, which is ideal in preventing the build up of charge in sensitive environments. With high spec ball journal bearings these electro conductive casters and wheels make moving sensitive equipment an easy solution .
