Black Diamond stoppers no. 1-13, strung on an OvalWire carabiner that should not be missing from your trad equipment.  All stoppers are lined up on an OvalWire carabiner and colour-coded. This makes it easy to distinguish between the different sizes. 

The Stopper Set Pro from Black Diamond includes stoppers 1 to 13 and thus has a range of variation from 7 to 71 grams. The wedges number 1 and 2 are only used for technical movement.

The transverse taper provides numerous opportunities in open, shallow or parallel cracks.

To increase the contact surface on the rock, the smaller clamping wedges have straight sides. The 8-13 wedges, on the other hand, have rounded edges for faster dismantling. In addition, each individual stopper is equipped with a drop-forged, durable steel cable.

Features:
• Durable aluminum heads and steel cables
• Transverse taper is versatile in flares, constrictions and parallel cracks
• Rounded edges for easy cleaning (smaller sizes are straight for better surface contact)
