<p>PROBLEM TO BE SOLVED: To facilitate draw-out work of a cable from a pull box, by fixing a ring to a main body in which shafts of a plurality of rollers are stepwise arranged and retained by a pair of plates, and installing the ring so as to be adapted to a piping port in a pull box for electric wiring. SOLUTION: A main body is formed by bridging stepwise shafts of a plurality of rollers between a pair of almost fan-shaped retaining plates. An attaching part of a ring is fixed to the lower part of the main body. The ring is adapted to a piping port of a pull box for electric wiring and arranged in the box. When a cable is drawn out from the pull box to an exposed piping, the ring is adapted to the piping port, and a plurality of the rollers are set vertically to the drawing-out direction of the cable, which slides on the rollers and is drawn out to the outside. As a result, the cable can be easily drawn out, and man-powers and man-hours can be reduced.</p> |
