When should I choose a 4.5mm duct rod instead of a 4mm or 6mm?
A 4.5mm cobra duct rod offers more stiffness than a 4mm rod, making it easier to push through ducts with mild bends, while still being lighter than a 6mm rod. It’s a good middle option for short to medium runs.
What lengths are available for the 4.5mm cobra duct rod?
Can I use pulling ropes with a 4.5mm duct rod?
Yes, duct rods are commonly used to feed pulling ropes through ducts before attaching the cable. Pairing the rod with a correctly sized rope helps reduce friction and makes cable handling more efficient.
Are cable socks useful with 4.5mm duct rods?
Cable socks are recommended when pulling cables to prevent damage and maintain grip. Our cable sock collection includes single, double, and triple eye models suitable for different cable sizes.
Do I need lubricants when using a 4.5mm cobra duct rod?
In longer or tighter ducts, using cable pulling lubricants can make the process smoother by reducing friction, which protects both the duct rod and the cable during installation.
