4 x 4-1/2 inch top-plate casters for warehouse carts on epoxy and smooth concrete. You will see wheel diameters 4 in, polyurethane treads, and capacities 1,000 lb across the SKUs listed below. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
