Petzl SMD Twist Lock Carabiner

A compact, lightweight locking carabiner with an automatic Twist‑Lock gate for sport climbing, general climbing use and attaching belay devices to a harness. Its asymmetrical D shape and H‑section profile balance high strength with reduced weight.

Main features

• Automatic Twist‑Lock gate allows quick one‑handed locking and opening.
• Asymmetrical D shape increases major‑axis strength and improves handling.
• Keylock nose prevents snagging on loops, rope or other hardware.
• H‑section cross‑section reduces weight while maintaining structural strength.
• Small lower hole accepts accessory attachment (e.g. Tibloc or Micro Traxion on a cord).

Suitable for sport routes, via ferrata and routine rock‑climbing protection; also practical when used with belay devices such as the GriGri. Designed for year‑round use and for handling with or without gloves.
