Ball Nutz by Trango are thin crack protection at its finest. Using a sliding ball/ramp concept - Ball Nutz will protect parallel sided cracks - flares - pin scars and bombays from 3 mm to 16 mm. The three smallest sizes have a 2:1 expansion range - resulting in unmatched security in chossy rock or expanding flakes. The # 4 and # 5 sizes will make you wonder why you ever used tiny cams. While these units are excellent for clean aid (they were even used for the first clean ascent of the Shield) - they're also terrific for protecting free climbs. Because of the stiff cable - we recommend using a quick draw whenever Ball Nutz are used to protect free climbing.
