The GMP 91228 Toneable Continuous Duct Rodder is built for professionals who need to accurately trace and locate underground ducts without excavation. This 3/8 inch (9 mm) fiberglass rod features an integrated 18 AWG copper conductor that carries a detectable signal when connected to standard signal transmitters and receivers, enabling quick and precise conduit mapping. With a 500 ft (152 m) rod length, it’s ideal for medium to long conduit runs in telecommunications, fiber optic, and power utility applications.

Engineered for rugged performance, the 91228 features a high-visibility orange rod housed in a durable, powder-coated tubular steel carrier. Its large airless tires provide excellent stability on uneven surfaces, and the integrated hand-operated brake offers smooth payout and retrieval control. Designed for long-term field reliability, this toneable duct rodder combines strength, flexibility, and precision for demanding underground locating operations.
