Piu 2 Belay Device

The long evolution of belay and rappel devices has culminated to a truly superior species with the Cassin Piu 2 Belay Device, which handles just about any situation or rope size you'll encounter. The genius two-hole design permits use with fat singles and skinny twins and safely belays one or two climbers from a top anchor on a big wall, while it is perfectly capable of plain-Jane sport routes after work.


  • Versatile belay device for sport, trad, multi-pitch, and alpinism
  • Thick forged aluminum lasts a lifetime and disperses heat quickly
  • V-groove grabs ropes without letting them get under each other
  • Diagonal cable prevents rope jams
  • Becomes a rope-tensioned auto-locking device when belaying from a top anchor and lowers easily when using an extra carabiner as a lever
  • Item #CSN001W
