Fiberglass Rodder Apply for Pulling Cables and Lines In Conduit, Duct
Duct roddder also called as fiberglass rodder, fiberglass duct rodder, fiberglass conduit rodder. The fiberglass rod is the basic element of the duct rodder. we add large proportion of high quality glass fiber (80%) for duct rodder. This special material make sure the rodder of high tensile strength and stability under shear stress. What’s more, we embed high density and UV-resistant polyethylene together to form a compact bound core, for protecting and insulate the fiberglass rodder from scratch while sliding in duct.

Manufacturing Process of Fiberglass Rodder
Usually, a rodders come complete with two mainly parts of fiberglass rod and frame. Firstly, the rod we produce two types for different application. One of the rod is fiberglass inner core and PP sheath for standard fiberglass rodder, the other kind of rod is fiberglass core with copper inner wire and PP sheath for traceable fiberglass rodder. And we product the frame to wheeled and without wheels, and we design both kinds of the frame with tubular steel alloy and a hand brake system.
Standard Fiberglass Rod come complete with three parts as alkali-free glass fiber, PP sheath and copper head
alkali-free glass fiber: that is the top-quality, but the price is higher, this material threading device is more durable, resistant to bending, good toughness, not broken, corrosion-resistant, long service life, that will make sure of the rod appear high strength and density in fiberglass rodders.
polypropylene (PP) sheath:Polypropylene, also referred to as PP, is a form of thermoplastic. Polypropylene have good ESCR performance, weather ability, abrasion resistance and excellent electric property. And we make polypropylene granules for rod sheath.
copper head: which mainly responsible for protect the end for rod, as itself advantage of corrosion resistance and flintiness, make the end free from broken.
Additionally, electric copper wire was especially designed for traceable duct rodder if some special task in complex conduit needed. the inner core is inserted with copper wire, which has excellent traceable performance.
We product all rodder frame with tubular steel alloy, hand-operated brake, rod guide, the wheel is optional.
