A duct rodder, which is also known as conduit rodder is a type of cable-pulling equipment that has a smooth and resilient surface. This is to facilitate the easy pass-through of the piercer through the narrow pipeline. The rod is typically made from extruded fibreglass and strong resin for great tensile strength and flexibility. In order to make the exterior part resistant to ultraviolet rays, high-density plastic material is used as well to protect and insulate the rod while it slides on the surface.
In order to work at its best, it is equipped with numerous accessories, including the following.
Tapered head: this is being attached to the end fitting on the duct rod and guides it through the conduit while allowing a pull line to be connected to the duct rod. The tapered head comes standard with the duct rodder.
Swivel coupling: this accessory is needed when one end of the duct rod is not sufficient enough for the entire conduit to run along the line. It is used to connect two duct rods that will be pushed into the conduit from the same end.
Shackle fitting: this is used to fit onto the tapered head, providing a larger pulling loop for connecting the pull line.
Threaded end fittings: these are replacement parts when the factory-installed ones have broken off or when the duct rod itself has broken down near the end of the rod. Usually, there is a manual that comes with these end fittings on how to install them and most of the time, epoxy is used for its installation.
Roller guide: the role of this accessory is to guide the duct rodder around misalignments, sweeps, and bends, or in cases where other cables are already occupying the conduit.
Splice kit: this kit is needed to fix the rodder once it breaks and usually includes the installation manual and epoxy for the repairs.
