As the particularity of rod moving in duct, small rod in large duct will make a higher pressure contact with the ducting; the same rod in smaller conduit will make less pressure on contact and therefore less friction, which can be pushed further. And we recommend mini cobra duct rodder for 20 mm-38 mm conduit, and cobra duct rod for 38 mm-150 mm conduit.The chart below is a rough guide as to rod diameter selection, but the about factors should all be taken into consideration before making the final selection.
