The anti-torsion cable makes the connection between the two elements of a flying sail furler: the drum and the top-swivel.
In a perfect world, the anti-torsion cable must transfer the torque from the drum to the top swivel (one turn in the drum resulting in one turn of the top swivel). These cable are usually supplied with the sail (within the luff for straight luff sail or separated from the luff for loose luff sails).
Virtual Rigger stocks anti-torsion line of the most common diameter (9, 13 and 15 mm). These AT line are supplied to length (meaning without any thimble nor clamp).
Anti torsion ropes usually can't be spliced. They have to be sewn, wedged or adjusted with clamps. All those clamps have been only designed for top down furler anti torsion loads.
