A D-shaped locking carabiner that's lightweight, compact and can be used in numerous situations, the Petzl Sm'D Triact-Lock carabiner is easy to manipulate, even when wearing gloves.


  • D shape provides efficiency in any situation, thus responding to multiple uses: connection of a belay system to a pulley, or to the end of a lanyard
  • Keylock system avoids any involuntary snagging of the carabiner
  • H profile contributes to better grip when wearing gloves
  • Hole for connecting TIBLOC or MICRO TRAXION type devices, limiting the risk of losing them
  • Triact-Lock automatic locking with triple-action gate opening
