Rigid caster wheels can install onto the bottoms of industrial carts, ladder stands, and other portable devices. These heavy duty casters can support a large working capacity range, and have different diameters. We carry steel constructed casters for heavy loads, and casters made from a rubber polyurethane material that allows the wheels to glide smoothly across different types of flooring. Our swivel casters make heavy carts easier to transport by efficiently switching directions to maneuver around corners. Be sure to view our other caster accessories such as caster socket brackets and brake kits, to see which parts will work best with your portable devices.
