I use this as a stopknot.PS it stretches.Tie a stop knot on your mainline and pull it tight,trim the tag ends,it slides easily through your rings.The knot can be adjusted to any depth required.Assemble in this order,determine what hook length you require and tie a small barrel swivel to it,slide a bead onto your mainline below the stopknot,slide whatever size float you want to use onto your mainline followed by appropriate weight,ball, coffin or whatever,finally add a bead to stop weight hitting the swivel knot and damaging the line,tie the mainline to your hooklength swivel and you are good to go.
