AFTCO Flat Line Clips are designed to be attached to the transom of the boat to allow you to lower the angle at which the line enters the water. This works well for trolling lures closer to the boat, keeps active lures in the water, and works well to keep lures in the water during rougher sea conditions. The roller release allows lines to be adjusted while in the clip, yet instantly releases when a strike occurs. The knurled knob in the center of the clip allows for release tension adjustment. Clips come fitted with 135# nylon coated cable and a heavy duty snap swivel allowing for a variety of mounting locations and options.
