The Petzl Sm'D twist-lock autolocking carabiner is lightweight, compact and allows for quick openings when you need to connect a Grigri® or other device.


  • Versatile D shape is efficient in a variety of situations, whether you're connecting to a belay system, a pulley, or the end of a lanyard
  • D shape and H profile provide good handling and grip, even when wearing gloves
  • Keylock system helps avoid any involuntary snagging of the carabiner
  • Twist-lock is ideal when quick openings are key and when connecting a Grigri (sold separately) to the harness
  • Hole allows a Tibloc or a Micro Traxion to be connected to the carabiner with a cord, making these devices loss-proof
