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