Cobra Duct Rod

Cobra duct rod that is also named cobra conduit rod, is an good cobra cable puller. It is widely used in various kinds of electric cable pulling pipe line project such as traction guide ropes, armored communication cables, power cables, network cables and video cables. You can also use the traceable duct rodder measure the length of the pipe, clear the pipe, and check the pipe. The simple operation, smooth surface, reasonable combination of toughness and strength are important and highly effective auxiliary tools in pipeline construction.


Cobra Duct Rodder

Cobra Duct Rod is the highest quality rod. It gains extra strength through a unique construction process, ensuring greater rigidity and strength, allowing it to withstand the extra forces required for long pipe runs with multiple bends and sweeps. A braided wrap of reinforcing fibers adds to its rigidity and helps bond the core to the outer plastic coating. The coating is made from a polymer blend for increased toughness and superior abrasion resistance to ensure an exceptionally long service life.

  • Features

  • The fiberglass reinforced rod and the rugged abs layer made the duct rod long-service time and flexible.

  • Assembly: metal frame and rubber wheels, Wheel assembly for easy transportation; Guide rollers and the right parts for rotary coupling; parking brake for the flexible rod. The cobra duct rod assembled by fiberglass rod,  galvanized steel frame and rubber wheels. The wheels make the duct rod transport more easier, the duct rod parts such as rotary coupling, parking brakes and flexible rod can let the users handle the duct rodder freely.

  • If the duct rod's diameter more than 8mm, the copper wire will be inside the rod to help users tracking easily.

  • The cobra duct rodder's rubber wheel let the duct rodder's moving more light and easily used in the field.

  • Feed device allows rod to be pushed, stopped and draw back more easier.

  • The Rugged tubular steel reel can be adjusted according to the site.

  • Anti-rust pulling eyes allow duct rodder long time using and for underground duct workable.

  • Advantages

  • Anti-rust and anti-corrosion.

  • Excellent tensile strength rod.

  • Frame made high quality steel, strong and durable.

  • With the wheels, the duct rodder can save much time and labor, improve the work efficiency.

Notice When Using the Cobra Duct Rods

1. The cobra duct rod should be used properly and regularly. The traction head must be protected (one end of the fiberglass duct rodder, material is copper-plated, with threads on it, which can be tightened tightly) , but cannot be broken.

2. When used, the traction head is first aligned with the movable pulley on the duct rodder frame, and the pulley is to carry out threading, pulling the wire, and clearing the pipeline. If you are trying to pull all the rod out of the frame, you should pay special attention to the last one is stuck in the ring which is on the small frame, this ring is used to fix the traction head when the duct rodder receives the rod.

3. You should not break the traction head when you pull it out. When you insert the threader, you must first snap the traction head in the middle of the ring.

4. The fiberglass duct rod has a hard and brittle material property, so you should keep the minimum diameter of the bend during the use process not lower than 60 cm. In the pipeline or other construction environment, if the pipe angle is right angle or less than 90 degrees. In this case, special attention should be paid to protecting the traction head from being broken. When pulling out of the pipeline, certain precautions should be taken to prevent the threader from being damaged. (such as placing a pay-off pulley for use in corners, etc.)

5. The permissible temperature range of the FRP duct rodder is between -40 and +80 degrees. Any improper behavior during construction should be avoided. For example, after using the duct rodder under environment for long time, it  should be placed in a cool place. Avoid prolonged sunlight exposure and rain showers.

6. The maximum rod traction for FRP duct  is 2.5 tons. Do not use high-powered machines for traction in a 90-degree right-angle environment. Otherwise, cracks may occur. Never allow vehicles and other heavy objects to be rolled, as this will greatly shorten their service life.

7. When using duct rod  in large-scale cable construction, do not use duct rod to directly pull the cable. Use a metal traction head of  the cobra duct rod to pull a wire rope first in the pipe, and then use a wire rope to pull the cable. The life of the cobra duct rod will be greatly improved. It is recommended to use various pay-off pulleys to increase work efficiency and protect the threader.
