Designed for even longer conduit runs, the Klein Tools 200-foot (60.96 m) Fiberglass Fish Tape is flexible enough to glide over existing wires in crowded conduit, but stiffer than other non-conductive fish tapes. The 17-Inch (432 mm) case diameter allows user to reel in 10-percent more tape in a single revolution than 16-Inch (406 mm) diameter fish tape cases, saving time and effort.
