A Grigri (styled as GriGri or GRIGRI) is an assisted braking belay device manufactured by Petzl designed to help secure rock-climbing, rappelling, and rope-acrobatic activities. Its main characteristic is a clutch that assists in braking under a shock load. The success of this device has led to grigri becoming a common name for
One of the most popular devices, a Grigri, when properly used, assists in braking the rope with a camming device that clamps the rope in the event of a fall. Because of the braking mechanism, modified belay techniques are widely used, though Petzl, the device's manufacturer, has approved only certain techniques for instructing new belayers.
This device utilizes a large surface area in contact with a climbing rope to provide sufficient friction along with the proper technique to be used as a belay device or for rappelling. A figure 8 (sometimes just referred to as an 8) is used in conjunction with a climbing harness and locking carabiner to control a belayed climber's descent, or ...
The range of modern belay devices also includes auto-block devices (e.g. the GiGi) allowing the belay device to be attached to a separate anchor point (e.g. and not to the belayer, which is useful for bringing up the second-climber on multi-pitch routes), and active assisted-braking devices (ABDs) that will self-lock with sudden rope movements ...
A belay device is a piece of climbing equipment that improves belay safety for the climber by allowing the belayer to manage his or her duties with minimal physical effort. Belay devices are designed to allow a weak person to easily arrest a climber's fall with maximum control, while avoiding twisting, heating or severely bending the rope.
Rope-solo climbing or rope-soloing (or self-belaying) is a form of solo climbing (i.e. performed alone without a climbing partner), but unlike with free solo climbing, which is also performed alone and with no climbing protection whatsoever, the rope-solo climber uses a mechanical self-belay device and rope system, which enables them to use the standard climbing protection to protect ...
The auto belay is fixed to the top of the route and the climber clips into a wire that pays out from the device, which enables the device to belay the climber as if they were on a top rope. Top roping with auto belay devices is the format used in competition speed climbing and in the speed elements of competition ice climbing. [12]
It's also the most common belay system which locks with the brake hand in line with the load, and as such is a more suitable method for direct belays than using a normal belay plate. [5] This can be useful when the anchor, carabiner and Munter hitch are above or behind the belayer whilst attention is paid to the loaded end of the rope.
