High strength spring steel fish tapes are stiff for long runs and are great for heavy duty wire pulls. Permanent, laser etched 1-foot (0.3 m) increments on the tape allow you to more accurately measure the depth of conduit runs and determine the amount of tape left to pay out. Polypropylene case and handle are extremely durable and offer the maximum in shock and impact resistance. Raised finger grips help transfer 100% of the winding power from your hand and fingers.
