Black Diamond Micro Stoppers are ultra-thin protection for aid climbing and thin trad lines. Copper-infiltrated steel heads fight shearing better than solid copper but are soft enough to prevent breaking the rock. The heads are swaged onto the cables, providing a more durable attachment than soldering. With Micro Stoppers you'll be able to sew up the thinnest cracks, even if you can't get your fingers in them. *Sizes 1 and 2 are meant for aid climbing only.
The Black Diamond Micro Stopper set 1-6 is an essential for thin cracks, seams and fissures. These stoppers are made of copper-infiltrated steel for an ideal mix of bit and durability, and patented swedged assembly increases strength.
