Jameson 13-140 (Millennium part 526104) is a compact duct rodder component, 11 in by 9.5 in and just 0.12 lb, engineered for Jameson fiberglass rodder systems used to prove conduit and place pull line ahead of fiber and copper cable. Fiberglass rod resists kinking and stays rigid enough to push through long conduit runs while flexing around sweeps and offsets. Spec sheets and supporting documentation are available on the product page for engineers matching components to an existing rodder. A practical spare for underground crews working manholes, handholes and street-level duct banks.
