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. GMP introduces the ultimate solution for durability and performance with our duct rodders, now enhanced with large airless tires on all 3/8 and 1/2 inch models for superior stability on rough or uneven surfaces. Designed to deliver exceptional value, these rodders are crafted from high-visibility orange rod material, offering the ideal combination of tensile strength, modulus, stiffness, and bending properties, proven through decades of in-field use. When loaded onto GMP's durable yet maneuverable dispenser/carriers these duct rodders are fundamentally essential tools for underground tasks such as cleaning and locating ducts, threading lines or pulling cables.
