Match a 4 x 4-1/2 top plate when bolting casters under warehouse carts on epoxy and smooth concrete. Catalog chips cover wheel diameters 4 to 10 in, polyurethane treads, and capacities 600 to 3,000 lb. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. Larger plates spread bolt stress on thick frames under continuous tow abuse. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
