What it is and why I tried it

I spend a lot of time pulling multiple THHN/THWN conductors through conduit, and I’m always looking for ways to avoid the dreaded “tape football” at the head of a pull. The Gisafai wire‑pulling heads are a simple alternative: thin stainless plates with triangular openings that capture individual conductors without stripping or taping. Each head has holes at both ends and a small clip, so you can attach a fish tape or rope on one side and pull a trailing line on the other. The set includes four identical heads, each roughly 4.8 x 0.47 x 0.06 inches—think sturdy feeler-gauge steel, long and narrow.

I put them to work on a few real pulls: a pair of home runs in 1-inch EMT with multiple 12 AWG conductors, and a slightly longer pull in 1-1/4-inch PVC with a mix of 10 and 12 AWG.

Design and build quality

The design is almost deceptively simple. The triangular slots are the trick: feed a conductor through one hole and back through another so it dog-legs and locks in. With a slight pre-bend in the wire and a tug, the jacket binds firmly—no tape, no stripped ends. The geometry also lets you stagger the conductors along the head’s length to keep the bundle diameter small.

Material-wise, the stainless steel plates are stiff enough not to twist under load, yet flexible enough to conform to a gentle bend. They’re corrosion-resistant and wipe clean easily, which is nice if you’re working with lube or in damp conditions. The edges, on my set, were cut cleanly but not polished. Before first use, I spent a minute with a fine file and some emery cloth softening the perimeter and the slot edges; it’s a small step that pays dividends against snagging and jacket scuffing.

The included connecting clip is workable, but it’s the weak link in the system. Under moderate tension it held up fine, but on a longer pull with a tight sweep I could see the clip’s gate starting to open slightly. Swapping it for a small swivel or a beefier quick-link improved my confidence and reduced twist.

Setup and workflow

My setup routine settled into a rhythm:

• Deburr the head’s edges (one-time prep).
• Lay out the conductors in pull order—ground behind the hots, neutral where appropriate—then stagger their entry points along the head.
• Double-feed each conductor through adjacent triangles. For slick jackets, a slight S-bend at the entry helps them lock in.
• Leave 6–8 inches of tail beyond the head to avoid jacket creep.
• Attach fish tape or rope to the front hole; tie a thin pull line to the trailing hole if you want to leave a line in the conduit for the next run.
• Apply pulling lube as usual.

Once you’ve done it a couple of times, securing five to seven wires takes a minute or two—faster than building and shaping a taped head, and much cleaner to undo.

Performance in the conduit

In 1-inch EMT with two 90s, the head behaved well. The bundle stayed slim, fed predictably, and didn’t “shoulder” into the sweeps the way a taped cone sometimes will when it gets flattened. The stainless plate offers a smooth face that rides the conduit wall rather than digging in. On the 1-1/4-inch PVC pull with more conductors and a longer run, the benefit was even more obvious: less friction, a cleaner profile, and no unraveling mid-run.

Holding power was solid across 12 AWG and 10 AWG THHN. I gave the conductors a hard tug by hand before each pull; nothing slipped. After the pulls, I inspected jackets—no nicks, just minor burnishing where they bore against the slot edges. Deburring beforehand likely helped here.

Where the system is less happy is tight geometry. The plate length is almost five inches, so hard back-to-back 90s or small-radius bends in undersized conduit can cause the leading edge to find a shoulder. It will still go with good lube and patient, steady force, but it’s not magic. In tight runs, I found that feeding the stiffest conductor at the tip of the head (closest to the pull point) helps it bridge gaps and ride over couplings more easily.

Strengths and limitations

What I liked:
- Fast, tidy preparation with no tape and no stripped conductors.
- Staggered layout reduces bundle diameter and glides through sweeps better than a bulky taped cone.
- Two attachment holes enable both pulling and leaving a trailing line in one pass.
- Stainless construction resists corrosion and cleans up quickly.
- Four-pack format is practical—stage multiple runs or keep spares in the gang box.

What gave me pause:
- The stock clip is on the light side; it can spread under high load. I recommend replacing it with a swivel/quick-link before serious pulls.
- Edges benefit from a quick deburr. A minute with a file makes a noticeable difference.
- The length can be a liability in tight or small-diameter conduit; plan your route and consider conduit size and bend radius.
- These heads are purpose-built for individual conductors. They’re not ideal for NM-B/romex in open cavities, where the flat cable profile and staples/hole edges create different snag risks.

Practical tips

• Use a swivel between the head and your pull line to reduce twist and torque on the conductors.
• Stagger heavier-gauge conductors near the front of the head and lighter ones toward the rear.
• Pre-bend each conductor slightly where it enters the slots to increase bite without over-stressing the jacket.
• Lube the lead inch of the head and the first couple of feet of conductors.
• Keep the pull steady and linear; avoid pulsing or yanking, which can flex the head excessively and encourage the clip to spread.
• If you anticipate a rough run, run a sacrificial string behind the head so you can back-pull the head itself if it hangs up, instead of yanking on the conductors.

Durability

After multiple pulls, my heads show minor polishing and a few surface scratches, but no meaningful deformation. The plate springs back from gentle bends; I avoided forcing sharp kinks as the manufacturer warns. Treat them with the same respect you would a good fish tape leader—no prying or twisting—and they should last. Plan on upgrading the clip for longevity.

Who will benefit most

• Electricians and serious DIYers pulling multiple THHN/THWN conductors in EMT or PVC who want a faster setup and a slimmer head profile.
• Crews doing repeated home runs from panels and J-boxes, where staging several heads speeds turnover.
• Anyone who’s tired of cutting away bird nests of tape after a pull.

If most of your work involves NM-B in open framing, or you routinely pull through cramped, small-radius bends, the advantage narrows. You can still make it work, but a well-shaped taped head may be simpler in those scenarios.

Value

The four-pack offers good value. Even if you retire one after a tough pull or lose one in the chaos of a jobsite, you’re not out much. The time saved in prep—and the cleaner, more controlled pulls—quickly justify the cost. I do wish the factory would ship them with smoother edges and a heavier clip, but those are easy fixes.

Recommendation

I recommend the Gisafai pulling heads for anyone who regularly pulls multiple conductors through conduit and wants a cleaner, faster alternative to taped heads. They grip reliably, keep the bundle compact, and make it easy to stage repeat pulls. Deburr the edges, upgrade the clip to a swivel or quick-link, and respect bend limits, and you’ll get dependable performance from a simple, clever tool.
