The Grippa Stop has a ball-shaped end that works perfectly as a stop for small slip rings or to lock waggler floats in the correct position. Two Grippa Stops next to each other provide even greater security when casting with heavier sinkers, waggler floats and feeders .

The direction of the stop on the main line can also be reversed by first transferring it from the thread to a nylon loop, and then transferring it to the main line on the reel.
