19x7 & 18x7 |
Containing 19 strands, each strand is made up of 7 wires. It is manufactored by covering an inner rope of 7x7 left lang lay construction with 12 strands in regular lay. (The rotation resistant property that charcterizes this highly specialized construction is a result of the counter torques developed by the two layers.) When a fiber core replaces the steel wire core strand, the description becomes 18x7. |
