Roller Twin Gate
The Grivel Roller is a pulley integrated within locking a carabiner. It can be used to reduce wear and friction in many scenarios, such as top-roping and creates a simple system for ascending, hauling, self rescue and partner rescue. Generally it functions to make many jobs “lighter”. It comes in two sizes large, useful for hauling heavier loads, and small, handy for crevasse rescue when weight counts, and it halves the amount gear needed to be carried. Both carabiners come with the Grivel secure twin-gate safety system for effective self-locking. The small is for smaller diameter ropes up to 9mm, suitable for glacier rescue, the large can be used with ropes up to 11mm and is more suited to hauling.
