GMP duct rodders now come standard with length markings every 2 feet for easy measurement and large airless tires for enhanced stability on rough or uneven surfaces. Crafted from high-visibility orange rod material with an ideal combination of tensile strength, modulus, stiffness, and bending behavior, they are available in standard core or detectable copper core options. Rods come equipped with a male threaded end fitting and tapered head on the leading end, plus a female threaded fitting on the back end. When paired with GMP dispenser/carriers (tubular steel alloy, powder coated), they are used for cleaning and locating ducts, threading lines, or pulling cables underground.
