Spiral extruded polymer design reduces the amount of effort required to push or pull the fish tape through EMT or PVC conduit. Works great in either filled or empty conduit Best for use in up to 2 in conduit Two leader options - comes with either a 360 deg swiveling flexible metal leader (380 lb strength) or a non-conductive glow in the dark leader (220 lb strength) Faster, easier pulls - low friction design allows the tape to easily glide through the conduit without binding at turns, joints or couplings Spiral extruded polymer design does not rust and reduces the amount of effort required to push or pull the fish tape through EMT, IMC, rigid or PVC conduit
