Duct Rodders: The Duct Rod The rod is manufactured from state of the art materials formulated to offer the high performance and durability demanded by our customers. The core of the rod is manufactured by the Pultrusion process. This involves impregnating high strength continuous glass fiber filaments with a liquefied resin. The fibers are drawn into a heated die where the resin matrix is cured, bonding the fibers together and allowing mechanical load to be transmitted through the matrix and distributed amongst the fibers. The resulting pultruded rod combines both the high stiffness required to push the rod through long distances of ducting, with the flexibility to handle tight bends without damage. This inner core is then coated with a highly durable, scratch resistant Polypropylene sheath which protects the core from mechanical damage. The Frames The Frames are also a feature of the GMP systems. A larger footprint for stability； steel brake handles that will last forever； dual rod out-feeding positions and wheels inside the frame width. The two smallest sizes feature new frames with the feedout built into the handle. All frames can be laid down on either side. These are just some of the new design features that will make every unit more usable and friendly for the end user. Duct Rods - Selection Which is the right rod diameter for any given application? The rod selection is usually governed by several factors including: &#8226； The size of ducting it is to be pushed through &#8226； The distance the rod is to be pushed &#8226； The number and tightness of bends in the ducting &#8226； If the ducting is already occupied by cable
