The S4712B by Richmond is a swivel frame castor and features a nylon wheel. This swivel castor is one of our utility series range and can hold loads up to 70kg. The S4712B uses plain bearings for wheel rotation. The swivel frame allows the load to be steered. The diameter of the nylon wheel is 100mm, the wheel width is 25mm and can be ordered separately (NY4415). To order this castor without a brake, search for S4712.


Ideal for light duty applications including wire baskets, display equipment and light trolley applications, Richmond Utility Series Bolt Castors offers a corrosion resistant attractive zinc plated finish in a pressed metal construction. A choice of a nylon wheel or non-marking grey rubber adds to the versatility of this castor. The ability to add various pintle fittings for round or square tubing ensures maximum functionality and performance.
