The Klein Tools' 100-Foot Multi-Groove Fiberglass Fish Tape with Spiral Steel Leader is perfect for wire runs associated with commercial, residential and voice-data-video installations. The optimized housing and handle design decreases payout effort and reduces binding. A multiple-position handle allows for a firm, steady grip as you pull or rewind the tape. The unique interior case shape combines the leverage of square cases and the comfort of round cases, which makes rewinding tape after a long run easier. This fiberglass tape maintains a strong core for pushing power, but the multiple grooves provide less surface area therefore less friction for smoother tape feeding.
