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
