The GRIGRI's self-braking function helps the belayer catch and hold a climber, making it great for working routes. Works equally well for lead climbing and toproping. Ergonomic design makes for smooth, controllable lowers. Also great for rappelling on single ropes & perfect for setting and cleaning routes.
The GRIGRI is designed for indoor climbing or well-equipped sport climbing, not for alpinism or adventure climbing. Allows belaying and lowering of a climber even where the latter is heavier than the belayer. A handle allows easy control of the device and smooth running of the rope. The GRIGRI works on a similar system as a car seat belt, because it locks when tension is applied to the rope. When movements are slow, the rope runs freely through the device; - When there is a shock load, the GRIGRI locks, jamming the rope with a cam.
Usage is similar to that of conventional belay devices
giving/taking slack is done by using both hands to slide the rope through the device
falls are held by holding the free end of the rope with the brake hand
for lowering and rappelling, the rate of descent is controlled by the hand holding the free end of the rope (the rope is released with the handle)
- For use with single ropes only 10mm-12mm
- weight 225g
- Aluminum side plates
- Stainless steel cam and friction plate
- Reinforced nylon lever arm.
