Show Description

Ascender with a toothy cam that's self cleaning and grips solidly on muddy or icy ropes. Ergonomic design maximizes power when pulling with 2 hands, and it works with thick gloves and mashed up hands.

  • Chrome-plated steel cam with angled teeth is self cleaning, and secure on muddy or icy ropes.
  • Moulded rubber and plastic grip with a nylon catch. Ergonomic design keeps your hand from sliding to the bottom.
  • Improved cam grips wet or muddy ropes, yet slides up easily.
  • Safety catch prevents the cam from opening too far and losing the rope.
  • Recessed trigger is guarded from accidental opening on low-angle terrain. Can still be installed or removed with one hand.
  • 2 attachment points: wide lower hole accepts carabiners for lanyard and footloop, upper hole clips a carabiner around the rope.
  • Not intended shock loading or for self-belay setups.
  • Sold individually for left or right hand.
