How do you pull a wire through a short run of conduit?
A proper fish tape is 15 m of steel on a reel. The run you're doing is 600 mm through a wall cavity.
Applies to
- Process
- Wire pulling
- Materials
- Short conduit runs, cable channel, wall cavities
- Setup
- Long zip tie, tape, the wire you're pulling
- Not for
- Long runs, tight bends, or heavy multi-core pulls
Why it matters
A zip tie is stiff enough to push and flexible enough to take a bend, which is exactly the property a fish tape has. In a short run that's all you need.
The head gives you something to tape or tie the wire to, so the attachment doesn't come apart mid-pull. That's the part that fails with string.
What good looks like
- The tie comes out the far end without fighting
- Wire attached to the head with a smooth taper — no lump to snag
- One steady pull, not a series of jerks
How to apply it
- Push the tie through the run, head first or tail first depending on which end you can reach.
- Attach the wire to the head end and tape it into a smooth taper.
- Pull steadily from the other end.
- If it snags, back off and re-feed rather than pulling harder.
Exceptions & tradeoffs
A tie will buckle on a long run or a tight bend. Past a couple of metres, or through more than one bend, use a real fish tape.
Pulling hard on a snag strips insulation. Back it off, don't power through.
Common mistakes
- A lumpy taped joint between tie and wireTaper the tape so the joint is no fatter than the wire
- Yanking at a snagBack off and re-feed — a snag pulled hard damages the wire you're installing
