When should I use a 9mm cobra duct rod?
A 9mm duct rod on reel is recommended for longer duct runs or where added rigidity is needed to push through resistance. It’s widely used in utility, telecoms, and power installation projects.
Can I use a 9mm cobra rod with winches?
Yes. Many contractors use a 9mm duct rod to first feed a pulling rope through the duct, which can then be attached to a cable pulling winch for extra pulling power.
What accessories are recommended with 9mm rods?
Pairing your cobra rod with cable socks ensures cables are held securely. Using pulling swivel links also helps prevent cable twisting during installation.
How does a 9mm rod compare to smaller diameters?
Compared to 6mm or 4.5mm rods, a 9mm version is stiffer and stronger, making it more suitable for long distances and heavier cables. Smaller rods, however, are often better in shorter or more confined duct runs.
