Trango BallNutz offer some climbers thier finest crack protection. Using a sliding ball/ramp concept, this pro will protect parallel sided cracks, flares, pin scars and bombays from 3 millimeters to 16.
The three smallest sizes of these sliding nuts have a 2:1 expansion range to secure 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, Trango recommends using a quickdraw to protect free climbing.
