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 non-conductive eyelet tip offer added protection against shock from energized sources. Multiple grooves molded into the fish tape provides less friction in conduit with or without wires for smoother tape feeding updated model Cat. No. 56383 available
