Definition & Meaning of "fish tape"

What is "fish tape"?

Fish tape is a long, flexible tool used by electricians and plumbers to pull wires or cables through pipes. It is typically made of steel, fiberglass, or plastic and is wound on a spool. Fish tape is pushed or fed into a pipe, and when it reaches the desired location, the wire or cable is attached to the end of the tape. The fish tape is then pulled back through the pipe, bringing the wire or cable with it. It is commonly used in construction and repair work to install electrical wiring or plumbing lines in hard-to-reach areas.
