The GMP Tools Duct Clamp Assembly (P/N 34639, Millennium part 554464) is a factory-fit replacement clamp for the GMP eRodder (P/N 77000), securing sub-duct in place while the eRodder installs microduct into an existing conduit. Crews rely on a tight clamp here to keep the eRodder tracking straight during a placement run. It's a direct spare referenced in the eRodder manual for techs servicing the machine in the field. Stock it with other eRodder spare parts and motor drive belts for the same equipment.
