Stopper Set

Since 1971, Black Diamond has been refining the exceptional geometry of its Stoppers to provide micro-protection that stays put. Their bomber performance ushered in the age of clean climbing and has made them a staple of every climber's rack for nearly three decades. Rounded corners assist "cleanability," reducing the possibility of the nuts getting caught on irregularities inside cracks.


  • Original collection of Black Diamond's stoppers
  • Time-tested shape with transverse taper for versatile constrictions
  • Rounded edges assist with easy cleaning
  • Includes Black Diamond's HotWire Carabiner
  • Item #BLD0121

works as expected

this range or stoppers made the most sense for me as a beginner tradder, though I've recently found a use case for a #2

Work great

I struggle to remove them done times but I think that's kind of the point. They feel sturdy and are easy to trust.

Rock’n Nutz!!

BD Stopper set have been excellent. I started out just placing gear while learning to lead on a top rope with a tail at Devils Lake and Petenwell Rock in Wisconsin. I’ve put a high value on stopper placement on trad because of there utility and flexibility once you have the placement down. I highly recommend this product to anyone starting out in trad climbing!

I teach an intro to climbing anchors course. The BD Stopper Set is a true classic. The color coding sequence matches nicely with the rest of the BD anchor products. This set shows the kN forces that each stopper can take based on which surfaces are engaged in the rock. The BD Stopper Set was my first nut set 15+ years ago, and they are still my go-to as I bought a new set earlier this year. Perfect for anyone's beginning traditional rack.

Solid set of stoppers

exactly what you expect, a standard set of stoppers. No issues with integrity, pair these with a nut tool and add a valuable piece to your rack

Solid nuts, used in a few pitches and taken a few falls on them. Do what they need to do, would whip.

Old classic gets better

Great upgrade on an old standard with the anodized colors. Perfect for anything and beats leaving a cam in the event on uncharted alpine lines.
