| 19×7 | Containing 19 strands, each strand is made up of 7 wires. It is manufactured by covering an inner rope of 7×7 left lang lay construction with 12 strands in right regular lay. (The rotation-resistant property that characterizes this highly specialized construction is a result of the counter torques developed by the two layers.) When the steel wire core strand is replaced by a fiber core, the description becomes 18×7. |
