USA-Made and durable with an economical heavy-duty wheel, this 6" x 3" phenolic wheel swivel caster with face brake is high capacity and floor protective, but is not meant for use in wet or moist application.Our 75 Series casters are constructed from high quality heat-treated AISI 1045 laser-cut steel. A precision machined raceway combined with fully welded legs (inside and outside) and kingpinless design delivers superior strength in rugged applications. Kingpinless casters eliminate kingpin failure ? the leading cause of caster failure.
