Gardner Bender Cable Snake Fish Tape is designed to make fishing short runs of wire in existing structures quick and efficient. I for pulling speaker and telephone wires under carpeting, down walls, and over ceilings, this fish tape is for installing electrical boxes, outlets, lighting fixtures, or security systems. Its aerodynamic tip reduces friction, which means less force is needed and fewer hang-ups during use. Measuring 25 feet in length with a tape width of 3/5 inches, it is made from durable steel and comes packaged in a convenient clamshell. Model Number: EFT-21PN
