Ironton 4in. Rigid Caster - Reliable Wheel Solutions

Humphries Casters offers a broad selection of wheel materials including phenolic, polyurethane, solid elastomer, rubber, steel, polyolefin, cast iron, thermoplastic, pneumatic, and high-temperature compounds. Each material is suited for specific floor conditions, load types, noise requirements, and environmental factors such as moisture or extreme heat.

These material handling casters are available with three mounting styles: top plate, threaded stem, and grip ring stem.
