Casters on the 4 x 4-1/2 plate pattern suit warehouse carts, racks, and everyday plant fixtures. You will see wheel diameters 4 to 12 in and cast iron and steel treads across the SKUs listed below. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.
