Fibreglass Drainer& Communications Rod
Duct Rodder& Fiberglass duct rodder& Duct rodAs one of biggest duct rodder manufacturers in Asia, we provide the duct rodder with high quality and competitive price. We could produce from 4 to18mm diameters’ duct rodder, and provide duct rodder adding with copper wire, stainless steel wire for detecting uses. So the duct rodder is also called Detectable Rodders. According to customers’ requirement, We could produce different length and clour duct rodder.
In the world , the duct rodder have different name:
Cobra duct rodder, Pipe Eel, FISH TAPE, Cable Handling Equipment, Cable Jockey, CONDUIT SNAKES, cables rodder, Duct rod/ Push rod , Fiberglass conduit rod reel , Duct rodder| Duct rodding| frp duct rodder
.
The Cobra duct rodder is the highest quality rod, designed for heavy duty applications. The extra strength comes from a unique construction process that ensures greater rigidity and strength, enabling it to endure the additional force required for long duct runs with multiple bends and sweeps.   
Duct Rodders are composed of fiber glass rod which was extruded by fiber glass and high strength resin at high temperature. This type of rod has high tensile strength and flexibility. It was covered by a high density polyethylene engineering plastic as its protect layer, which make duct rodder cover sliding on surface, durable, corrosion resistant and has good insulation performance, which make them safe for using in cable occupied duct.
High Density polyethylene ( Grade: for the insulating and jacketing of Telecommunication Cables) is used in the outer diameter coating.
Duct Rodders will equipped with different size reel according to the length of rod. There are wheels on the reel, which make it convenient for moving.
1-Light weight, durable, resistance to acid, alkali, aging resistant, corrosion resistant.
2-High tensile strength and bending properties, which make it to go through narrow pipes easily.
3-Good temperature adaptability, the product will not soften in hot weather/ nor become brittle in cold weather. Its usability will not be affected by temperature.
4-Outer protect layer are made of high density polyethylene engineering plastic, which has good anti-UV capability.
5-Cover was coated with long-term UV-resistant polyethylene.
6-Its surface has the advantage of smooth, wear-resistant and long service life.
7-There are meter marks on the protect layer of duct rodder, which can be used for measuring distance. Marks are printed by professional printing machine, which has the advantage of strong adhesion, clear writing, waterproof, anti-ultraviolet, it can be still clear even after using many times.
8-There are several kinds of colors for the rod for your chosen.
