The IDEAL Electrical 31-046 E-Class Fiberglass Fish Tape is non-conductive up to 1000 volts for use around existing circuits. The glow-in-the-dark molded eyelet offers greater visibility in dark areas while the fiberglass core provides column strength for greater pushing and pulling capabilities. The smooth nylon jacket protects the fiberglass material and assists in feeding through runs with multiple bends or in multiple planes. The round shape of the jacket provides omni-directional pushing through tough bends. With the 3/16 inch overall tape diameter, a pulling strength of up to 350 pounds is provided. For added ruggedness, the Tuff-Grip Pro handle keeps dirt and moisture out of the tape and works to withstand multiple drops from 25 feet away onto concrete.
