The Fremco DuctRod machine, part 101-230320001, is a powered rod pusher for driving duct rod through conduit ahead of a fiber optic cable pull or blow. Mechanical push replaces hand-feeding rod, which lets crews proof longer runs, clear partial blockages and get a pull line through bends that defeat manual rodding. It pairs with Fremco hydraulic power packs and the DuctRod fixing hook to anchor against push reaction at the duct mouth. Specified by contractors doing conduit proofing and rope placement. Millennium part #540484.
