REVERSO is a versatile belay/rappel device that accommodates all single rope diameters from 8.5 to 10.5 mm. In Reverso mode, it is used for belaying one or two second climbers. The special design of the rope slots allows the rope to glide smoothly and reduces wear.

  • Ropes glide smoothly through the device
  • Reverso mode, for belaying one or two seconding climbers
  • Independent and simultaneous belaying of two seconds in Reverso mode
  • While belaying in Reverso mode, a carabiner placed in the release hole allows the belayer to give slack when the device is under tension
  • Rope installation diagrams for belaying and Reverso mode are engraved on the device
Compatible with all single dynamic ropes 8.5 to 10.5 mm
V-shaped friction grooves enable controlled braking
The rounded design of the rope slots limits wear and extends the life of the device
