The Jameson Wee Buddy Fish Tape with 50 Ft. of 1/8 in. Fiberglass Rod is ideal for pulling phone wire, network cable or speaker wire through walls and occupied electrical conduit. Due to the round rod design, this non-conductive fish tape slides easily over existing wires, especially at bends, with a smooth, non-binding payout and return. The easy-grip canister, along with the exceptional bending strength of the flexible rod, make this heavy-duty fish tape an excellent choice for professional use or your D.I.Y. projects.
