High strength steel fish tape glides between surfaces for effective pushing and pulling of wire under carpets, through insulated walls and over suspended ceilings. Permanent, laser etched 1 ft (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 percent of the winding power from your hand and fingers.
