The Klein Tools' 100-Foot 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. The tape features laser-etched descending markings placed at every foot. These markings allow you to accurately measure the depth of conduit runs and determine the amount of tape left to pay out.
