This 80mm braked castor is made of a zinc plated housing which ensures the castor is robust enough and suitable for a variety of environments. The swiveling castor, with the non marking grey rubber wheel and a brake is suitable for trolleys, equipment and general purposes. The non marking grey rubber wheel with roller bearings means the castor is quiet to move, will not mark the floor. The foot operated wheel brake simultaneously brakes both the swivel castor head and the wheel. 80mm Swivel Braked Castor Grey Rubber Wheel
