Match a 3-1/8 x 4-1/8 top plate when bolting casters under carts that must lock wheel and swivel together. Typical builds show wheel diameters 2-1/2 to 6 in, polyurethane, phenolic, and nylon treads, and capacities 120 to 850 lb. Replace worn corners in matched sets when possible so the cart tracks straight under load. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs.
