Black Diamond #4 Stopper -

Stoppers are the foundation of any climbing rack and these are the standard wired, wedge-shaped nuts for thin-crack protection. Black Diamond designed a transverse taper into the Stopper which permits good sideways placements in flares and shallow seams. This feature opens up previously unprotectable cracks, and makes Stoppers significantly more functional than other wedge-shaped nuts. The nuts are easier to remove since Black Diamond rounds-off the sharp corners that cause nuts to get hung up on crystals and irregularities inside the crack.


  • Anodized (colored) by size for quick identification


  • 7075 aluminum alloy is durable yet has plenty of bite to stay put
  • Classic design is light, strong, and easy to use.
  • Rounded corners allow easy removal
  • Transverse taper increases surface-area contact to provide best placements in nonparallel cracks
Time-tested passive protection, Stoppers are a direct link to the original chocks that started the clean climbing revolution. Black Diamond Wired Stopper #4 is an essential for every trad rack, designed to permit sideways placements in flares and shallow seams. Equipped with a durable, galvanized steel cable.

Black Diamond #4 Stopper Review:



Very nice product. Wears out a little easy. Also, you have to buy multiple of the same thing because you never know what size crack you are gonna be in. This will end up costing quite a bit
