Petzl Sm'D Screw lock

The Petzl Sm'D Screw Lock is a compact and versatile D-shaped screwgate carabiner for multiple uses such as belay systems, use with pulleys and lanyards.

The I-Beam structure of this premium climbing biner boosts both strength and durability while reducing weight to a minimum. A keylock gate reduces the chance of rope snag and a sleek but practical size allows for single-handed operation. Finally, the Sm'D Screw Lock, like all of Petzl's current locking carabiners, has a red visual indicator stripe to let you know when it's locked and comes in a distinctive yellow colour so you won't lose them if you misplace them.


  • D shape guarantees efficiency in any situation.
  • Great versatility for multiple uses: connection to a belay system, to a pulley, or to the end of a lanyard.
  • Compact and very lightweight.
  • H profile contributes to better grip when wearing gloves.
  • Keylock system to avoid any involuntary snagging of the carabiner.
  • A hole allows a TIBLOC or a MICRO TRAXION to be connected to the carabiner with a cord, making these devices loss-proof.
