Light- Medium Duty, Swivel Triangular-Mount Kingpinless Plate Caster; 500 lb. Load Rating, 4" Wheel Dia.

These light-duty kingpinless plate casters have triangular mounting plates and are suitable for applications where there is limited surface area for mounting the casters, such as when the casters will be mounted into a corner and there is no material on the inside area of the mounting surface for attaching a caster with a square mounting plate. Kingpinless casters with a triangular mounting plate typically have lower weight capacities and can tolerate less shock and impact than other types of kingpinless casters. They are often installed on tool boxes, gang boxes, worksite cabinets, and other light equipment that will be moved over flat surfaces.

Impact-resistant kingpinless plate casters do not use a kingpin to hold the caster together. They distribute weight more evenly, roll more smoothly, tolerate higher speeds, and have better resistance to impacts and shock forces than standard plate casters that are held together with kingpins. The casters' mounting plate attaches to the bottom of machinery, carts, or other equipment. The caseters allow the equipment to roll, which reduces effort when moving or repositioning it. Kingpinless plate casters are available in swivel and rigid versions. Swivel casters can rotate 360°, allowing equipment to change directions while rolling. Rigid casters roll in a straight line. Two rigid casters will often be paired with two swivel casters to allow the equipment to both maneuver around curves and obstacles and maintain a straight course while rolling. Kingpinless plate casters are used in aggressive applications where they will encounter shock forces and heavy loads or be moving at high speeds.
