The AFTCO Roller-Troller Outrigger Clip helps you position a trolling lure from an outrigger by simply reeling in or letting out line right through the clip,where the line rides safely on a roller that features silky-smooth action. The clip’s micro-tension adjustment is positive yet sensitive over a wide range of settings,and once the tension is set,our precision-engineered latching system releases your line repeatedly at exactly the same pull to assure fewer missed strikes and less broken line and gear.
