“McStopper” is an adjustable weight stop in ‘one step’, which eliminates swivels and two knots, the weakest point in Carolina rigging. Fast, strong, and easy to adjust leaders to any length without additional line or time to cut and tie knots. Simply squeeze the “McStopper” with needle nose pliers. When the slit in the center of the “McStopper” opens to an oval, thread the line through the opening and release the pliers. 8/pkg
