Accessories Used With the Duct Rodder

May 29, 2017

A duct rodder is used for pulling cables, cleaning and locating ducts and threading lines. Since it is sometimes used for underground tasks, it is made with corrosion resistant material. Duct rodders are lightweight for easy handling, resistant to weakening by UV radiation and they are unaffected by water in any way. They are found in different strengths and lengths.

They do not become brittle when exposed to cold weather nor do they lose their tensile strength in hot weather. Duct rodders are available in custom sizes. Therefore, when ordering your duct rodders, ensure that you accurately specify the diameter and length. This is because most manufacturers have a non-return policy for custom made rodders.

A duct rodder is usually used together with several accessories as listed below.

Flexible leader: This component is used in guiding duct rodders around misalignments, sweeps and bends.

Swivel coupling: This is used to connect two duct rodders when you run out of the rodder before reaching the end of the conduit.

Tapered head: It guides the duct rod through the conduit. It is attached to the end fitting of the duct rod.

Roller guide: This is used to guide the duct rod along sweeps, bends and especially where the conduit is already occupied by other cables.

Basket combination: It is used to connect two duct rodders that have been pushed into the conduit from opposite ends. It cannot negotiate tight bends. When the full length of the duct rodder is difficult to push from one end, it is used instead of a swivel coupling.

Splice kit: It is used to repair broken duct rods.

Threaded end fittings: It used when the duct rod breaks near the end of the rod or in place of the factory installed fittings when they break.

Note that it is advisable to use the exact size of duct rodders for the conduit size you are using. Using a larger size will not interfere with the bends, and as a result, a smaller size will buckle.
