Petzl Reverso 4


Ultra-light multipurpose belay/rappel device with braking adapted to different rope diameters and suppleness, including the Reverso mode. This belay/rappel device is lightweight and easy to use. V-shaped friction channels, with asymmetrical side grooves, adapt the rope friction for better control with half, twin and single dynamic ropes. Reverso mode for belaying one or two seconds.


  • Ultra-light design
  • Minimalist construction
  • 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
  • Adaptivee braking power on larger diameter ropes
  • Incremental 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
  • Improved 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 and will not twist the ropes regardless of the mode used
  • Separates the two strands of rope when belaying and rappelling on two ropes
  • Reverso mode aluminum attachment hole is easy to identify
  • eeper cable keeps the device from moving up the rope when belaying and reduces risk of losing the device
