Match a 4-1/2 x 6-1/4 top plate when bolting casters under warehouse carts on epoxy and smooth concrete. You will see wheel diameters 6, 8, 12 in, polyurethane and steel treads, and capacities 2,000 to 4,500 lb across the SKUs listed below. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. Larger plates spread bolt stress on thick frames under continuous tow abuse.
