Match a 4 x 4-1/2 top plate when bolting casters under bake carts, metalworking fixtures, and debris-heavy floors. Catalog chips cover wheel diameters 3-1/4, 4, 5, 6 in, polyurethane, phenolic, and polyolefin treads, and capacities 200 to 850 lb. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races.
