Klein Tools' Multi-Groove Fiberglass Fish Tapes feature a low-friction, easy feed design. The grooved profile and fiberglass core provide rigidity for long distances and less surface contact with wires when pushing through crowded conduit. The non-conductive fish tape and eyelet tip offer added protection against shock from energized sources.PRODUCT FEATURES:• Multiple grooves molded into the fish tape provides less friction in conduit with or without wires for smoother tape feeding.• Non-conductive fish tape and eyelet tip offer added protection against shock from energized sources.• The 17'' case diameter means you can reel in 10% more tape in a single revolution vs. a 16'' case.• Raised fingergrips help transfer 100% of the winding power from your hand and fingers.• The unique sloped handle optimizes the position of your hand for quick hand-over-hand rewinds and allows a more level payout of tape on the backswing while feeding conduit.• Made in the USA.
