18mm Big Diameter Duct Rodder

Features: 

1.constructed of fiberglass reinforced in the center and consists of a rugged plastic layer that would ensure the lifetime of the flexible rod. 

2. Excellent flexibility force. 

3. Tensile strength about 500 KGF. 

4. designed for heavy duty applications ensuring greater rigidity and strength, while supporting additional forces without resentment to the multiple curvatures. 

5. Wheel assembly for easy transportation. 

6. Guide rollers and the right parts for rotary coupling.
Rolling bearing cage flotation (reel transport) for mobility should be light and easy to use in the field, including a parking brake for the flexible rod.

18mm special size duct rodder 2 

Fiberglass special size duct rodders or push pulling rodders and commonly called fiberglass duct rodder its nature passing through under ground ducts by ups,  down negotiating the duct curvature thus very convenient to pull the cables, wires inside the duct , also it can be used to locate the duct block or damage portion identifications. it has high safety aspects to use underground applications because of its non conductivity of electricity, sets a major safety to site workers.

It has been built with rigid sturdy steel tubular fabrication for easy usage at site and can be self coiled in the tubular frame and easily roll like trolley on ground by its wheels fitted at bottom .
The ducts rodders normally comes in various diameters from 4.5 mm to  18 mm as per ground applications. The 18 mm duct rodder is a special size which is for large diameter tube and cable pole as the push-pull tools
