Black Diamond - Stopper Set Pro - Nut

The Black Diamond Stopper Set Pro are a must for trad climbers. The Stopper Set includes a complete set of Black Diamond's nuts. With the smallest weighing in at only 7 grams (No. 1) and the largest at 71 grams (No. 13), this stopper set has answer for every seam. The strength of these nuts ranges from 2-10 kN, but No. 1 and 2 should only be used for technical movement.

The nuts in the Black Diamond Stopper Set Pro are equipped with a durable steel cable and a tough aluminium head. They are also anodised according to size and easily identifiable.

The transverse taper allows for placement in flares, constrictions and parallel cracks. The stoppers No. 8-13 have holes to keep weight to a minimum, whilst the smaller nuts (No. 1-7) have a solid body. What's more, the stoppers No. 8-13 also have rounded edges for easy removal. The smaller nuts have straight sides in order to keep the contact surface as large as possible. The Black Diamond Stopper Set Pro will leave nothing to be desired!
