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
