The Black Diamond Stopper is a passive protection nut available in sizes 1 through 13, covering placements from hairline crack features through mid-sized horizontal seams. A transverse taper along the body allows sideways placement in flares and shallow seams where a straight-tapered nut would fail to seat. Each size is color-anodized for fast on-route identification, with rounded edges that reduce the leverage required for clean removal. The galvanized steel cable provides durability across repeated placements, and weights run from 7 grams (size 1) to 71 grams (size 13), making individual nuts a weight-efficient option for rack building across a range of crack systems.
