Conductive rubber tread materials offer excellent electrical discharging throughout the tread and across the whole contact surface. The steel bracket is Zinc coating so the whole caster is electrical conductive. The caster will then producing a continuous and safe discharging to ensure the safety of electronic devices.

Innovation of stainless caster: the design just as normal steel. Parts are all exposed so it is easier to wash and clean to prevent dust, thread and even bacteria staying inside the wheel like other Plastic frame casters.
