USA-Made and durable with an economical heavy-duty wheel, this 8" x 3" phenolic wheel rigid caster 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.
