The Klein Tools' 50-Foot Steel Fish Tape is perfect for wire runs associated with light commercial, residential and voice-data-video installations. The optimized housing and handle design decreases payout effort and reduces binding. The large handle allows for a firm, steady grip as you pull the tape from the housing. 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. Warnings: Wear approved eye protection when feeding, pulling or rewinding fish tape.; Do NOT use any fish tape on or near live circuits. Use extreme caution when working near any electrical equipment.; Use a safe work position to avoid loss of balance when using fish tape.; Never remove screws while fish tape is coiled inside reel.; Never form pulling loop into a single loop (into shape of a fish hook) or create a sharp edge that could cause fish tape to catch on other objects or cut into insulation of surrounding wires. Pulling loop should only be formed into a double loop. - Features: Durable 1/8-Inch wide steel fish tapes are firm yet flexible for large wire pulls; Optimized design of the tape housing decreases payout effort; Slip-resistant housing geometry improves winding power; Multi-position handle gives you a firm, steady grip as you pull tape from the case; Descending laser etched markings in 1-Foot (0.3 m) increments; Easy-to-read distance marks allow you to more accurately measure conduit runs and the amount of tape left to pay out; Polypropylene case and handle offer high impact resistance; U.S. Patents: 8164025; 8168921; 8212178; 9895773; 10099316; Optimized Housing Design; Optimized design of the tape housing descreases payout effort; slip-resistant geometry improves winding power; Made in the US with Global Components; Optimized design of the tape housing decreases payout effort; slip-resistant geometry improves winding power
