200mm Antistatic fixed castor with electrically conductive wheels made from polyurethane. Ideal for spark free environments such as clean rooms, laboratories and areas with highly sensitive equipment. This anti static castor can carry up to 400kg so is suitable in heavy duty environments as well. 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 polyurethane wheels make moving sensitive equipment an easy solution .
