High strength spring steel fish tapes are stiff for long runs and are great for heavy duty wire pulls. Laser etched markings in 1' (0.3 m) increments 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 offer the maximum in impact resistance. Raised fingergrips transfer 100% of the winding power from your hand and fingers.
