The Klein Tools 56351 is a 100-foot S-Glass fiberglass fish tape measuring 3/16 inch wide with a 7-inch spiral steel leader, suited for commercial, residential, and voice-data-video wire runs. S-Glass fiberglass material provides superior pushing power and durability while maintaining a low-friction surface. The optimized case design reduces payout effort and friction, and slip-resistant housing geometry improves winding power. A multi-position polypropylene handle provides a firm grip during pulling and rewinding. Laser-etched 1-foot descending markings enable accurate conduit depth measurement. Made in the US with global components. Weighs 3.4 lb.
How does the 100-foot 56351 compare to the 50-foot 56350?
Both share the same fiberglass body with spiral steel leader. The 56351 is rated for runs up to 100 feet, suitable for single-story commercial conduit and longer residential pulls. For runs under 60 feet, the 56350 is lighter. For 60–100 foot runs, the 56351 is the better match.
Is the spiral steel leader effective at 100 feet?
Yes — the spiral leader at the tip rotates as the tape advances in conduit, helping navigate 90-degree sweeps and standard bends at any tape length. The fiberglass body's flexibility becomes more pronounced at 100 feet, which is an advantage in conduit with multiple bends.
Can the 56351 be used in conduit already containing other cables?
The fiberglass body will not abrade other cables significantly, but the steel leader at the tip can snag or damage cable jackets if forced around tight turns. In conduit with delicate existing cable (fiber optic, data cable), use the 56383 (nylon tip) instead, which is gentler on existing conductors.
Why fiberglass over nylon or polyester at this length?
Fiberglass offers a better balance of push stiffness and flexibility than nylon at 100 feet. Polyester (such as the 50376) is more flexible and smooth but may lack the column strength needed for tight conduit at longer lengths. Fiberglass with a spiral leader is the proven choice for most commercial conduit work.
