Detailed description


  • Ultra-light design: - minimalist construction - hot-forged aluminum - weight: 59 g
  • A single device for all rope types: - effective braking on half and twin ropes (7.5 mm or greater diameter) - effective braking on single ropes (8.9 mm or greater diameter) - can belay the leader, one or two seconds and can be used for rappelling - independent and simultaneous belaying of two seconds in Reverso mode - for swapping leads (team of 2), offers a quick transition from Reverso mode to belaying the leader
  • The V-shaped friction channels: - give greater braking power on thin ropes - adapt the braking power on larger diameter ropes - increase the braking pressure on the ropes in Reverso mode
  • The asymmetric side grooves: - increase the braking power for leader or top-rope falls, or while rappelling - improve rope glide through device when taking up slack
  • Hole for releasing the device under load: allows a loaded device in Reverso mode to be easily and gradually released with only a carabiner
  • Rope friendly, facilitates rope maneuvers and rappelling: - will not twist the ropes regardless of the mode used - separates the two strands of rope when belaying and rappelling on two ropes
  • Intuitive use: - Reverso mode aluminum attachment hole is easy to identify - keeper cable keeps the device from moving up the rope when belaying and reduces risk of losing the device - usage diagrams (standard belay and Reverso modes) engraved on device
  • Use with symmetrical locking carabiners (Am’D or WILLIAM) to maximize efficiency


  • Weight: 59 g
  • Rope compatibility: - for half ropes (8 mm or greater diameter) and twin ropes (7.5 mm or greater diameter) and on single ropes (8.9 mm or greater diameter)
