Invented in 1987 by John Middendorf, Ball Nut have become the secret weapon of many aid and trad climbers. These little wonders will work in small parallel-sided cracks where the only other option is pounding a piton. Ball Nuts also work in pin scars and small flares where even modern micro cams simply won’t fit. Since they weigh so little, many advanced trad climbers keep a #2 and #3 on their rack at all times.
