Belay device for single ropes, with assisted braking. Works nicely with the Petzl Volta 9.2mm but made to work with 8.5mm to 11mm ropes.
It takes in rope very quickly and smoothly, and (with practice) can pay out quickly as well. The Grigri is designed to work from a belayer's harness, but has been (mis)used as a direct belay by experienced users who know that extra braking and careful monitoring is required. In this case it can integrate into a 3:1 hauling system( with the minimal addition of a rope clamp such as a Prusik loop or Tibloc plus karabiner and, maybe, a pulley).
We provide the Grigri in orange to assist in gear identification and to match the Volta rope!
