3" Gray Rubber Swivel Caster, Plate Mount with Double Lock
These casters feature a soft gray rubber wheel molded to a polypropylene hub with an oil-less bearing.

They are also low maintenance and have a tread design which offers good traction on wet floors. These 3" swivel double locking casters have a 2-1/2" x 2-1/2" plate and 150 lbs. capacity.
