<p>PROBLEM TO BE SOLVED: To provide a coil-like cable hanger for supporting a wiring cable in the case of wiring work in a town of a communication cable, etc., such as cable television and capable of executing the wiring work more safely and efficiently. SOLUTION: In a cable hanger 1, saturated polyester resin made element wires which are extruded, stretched and twisted are wound in a coil shape. Regarding the relationship between the twisting direction of the element wires and the winding direction of coils, the winding direction is made to left-winding when the twisting direction of the element wires is S, and the winding direction is made to right-winding when the twisting direction of the element wires is Z. The twisting pitch is made to 3-15 times of the diameter of the element wires. When being in use, by being in the state that a wiring cable 3 and a messenger wire 2 are inserted in the extended coil, the cable is supported.</p> |
