Black Diamond Stoppers

When you’re climbing at your limit, the last thing you need to be worrying about is the strength and reliability of your pro, right? What you do need are Stoppers® that are strong, versatile and easy to place. Our Stoppers have a unique transverse taper that allows them to be placed in bottlenecks, flares and shallow seams—features that were once thought unprotectable. Also, with their rounded-off corners they’re much easier to clean.

Individually tested before they leave our factory Transverse taper allows sideways placement in flares Easy to place and even better…easy to clean

MICRO STOPPERS Micro pro for micro cracks! Black Diamond Micro Stoppers are made out of durable copper-infiltrated steel, making them more durable and much stronger than the average brass nut. With this chemistry, our stoppers are less prone to shearing, but still provide the “bite” found in brass nuts. Also, our unique cable-swaging technique extends the life of our Micro Stoppers several fold over the traditional “silver-soldered” method found on others. When placing, give these tough SOBs a solid tug to set ‘em and pair them with a runner when “wandering pro” could be an issue. Give them a little tap to dislodge them before cleaning.
