Whether on the rock or on indoor walls, the Master Belayer Kit by Grivel is a reliable companion on any vertical adventure! This practical set comprises a classic tube-based belay device and an HMS locking carabiner. Thanks to its minimalistic design, this tuber is particularly suitable for single-pitch climbs on the rock, on the wall or indoors. With its V-shaped notches, the device creates high friction and thus relieves your fingers when stopping the rope. Moreover, the notches give you absolute control over the rope at all times. The lateral material savings prevent the device from overheating when lowering your climbing partner and save weight on the wall. But the Master Belayer Kit comes with one more lightweight feature: the Omega locking carabiner by Grivel made of ultralight Aluminum 7000. All these factors leave nothing to be desired and provide you with maximum safety, functionalism and hardly noticeable weight. Simply perfect!
