Fiberglass duct rodder
Duct rodder is composed of fiberglass rod which is extruded by fiber glass rod and high strength resin at high temperature. This type of rod has high tensile strength and flexibility. It is covered by a high density polyethylene engineering plastic as it protect layer, which make duct rodder cover sliding on the surface, durable, corrosion resistant and has good insulation performance. Which make them safe for use in cable pulling in the conduit.
Duct rodders will equipped with different size reel according to the length of rod. There are wheels on the reel, which could make it easy to move.
Features and benefits:
·Light weight, durable, resistance to acid, aging resistant, corrosion resistant
·High tensile strength and bending properties, which make it to go through narrow pipes easily.
·Good temperature adaptability, the product will not soften in hot weather/nor become brittle in cold weather. It is usability will not be affected by temperature.
·Outer protect layer are made of high density polyethylene engineering plastic, which has good anti-UV capability.
·cover was coated with long-term UV-resistant polyethylene.
·it surface has the advantage of smooth, wear-resistant and long service life.
·There are meter mark on the protect layer of duct rodder.
·The length is 100m to 400m.
·There are kinds of colors for the rod to choose.
