Multiple grooves molded into the fish tape provides less friction in conduit with or without wires for smoother tape feeding. Durable 7 inch spiral steel leader helps push through crowded conduit. The 17 inch (432 mm) case diameter means you can reel in 10% more tape in a single revolution vs. a 16 inch (406 mm) case. Raised fingergrips help transfer 100% of the winding power from your hand and fingers. The unique sloped handle optimizes the position of your hand for quick hand-over-hand rewinds and allows a more level payout of tape on the backswing while feeding conduit.
