Each pack of 10 Composite Leadclips comes with an intergrated Quick Change Swivel to ensure the lead will be ejected and the leadclip won't "travel" up the mainline. Simply tie your mainline or leader to the eye of the leadclip using a 4 turn grinner or palomar knot, or splice your leadcore directly to the leadclip eye. Attach your rig to the quick change swivel and using one of our leadclip tail rubbers to secure the lead in place. We also recommend using one of our 54mm soft Anti Tangle Sleeves to help push your rig out straight on the cast.
