Fiberglass Fish Tape. Permanent, laser etched 1' (0.3 m) increments on the tape allow to more accurately measure the depth of conduit runs and determine the amount of tape left to pay out. Non-conductive, fiberglass fish tape slides easily over existing wires and through multiple bends. The lightweight and strong fiberglass tape resists harsh elements and is strength rated up to 500 pulling pounds. The 17'' (432 mm) case diameter means can reel in 10% more tape in a single revolution vs. a 16'' (406 mm) case. Durable 7'' (178 mm) leader helps push through crowded conduit. Raised fingergrips help transfer 100% of the winding power from the hand and fingers. Raised fingergrips help transfer 100% of the winding power from the hand and fingers. The unique sloped handle optimizes the position of the hand for quick hand-over-hand rewinds and allows a more level payout of tape on the backswing while feeding conduit. Made in the USA.
