This 30 series aisle groups plate-mount casters built for heavy warehouse carts, die carts, and plant fixtures. You will see wheel diameters 4, 5, 6, 8 in, polyolefin treads, and capacities 700 to 1,200 lb across the SKUs listed below. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Larger plates spread bolt stress on thick frames under continuous tow abuse.
