Aluminium body Imported MULTI-PURPOSE VERSATILITY: Designed for cragging, multi-pitch, and mountaineering; allows for belaying a leader, rappelling, and belaying one or two seconds from an anchor. REVERSO MODE (GUIDE MODE): Provides assisted braking when belaying one or two seconding climbers from the top of a pitch; allows for independent and simultaneous belaying of two seconds. WIDE ROPE COMPATIBILITY: Compatible with single ropes (8.5 to 10.5 mm), half ropes (7.1 to 9.2 mm), and twin ropes (6.9 to 9.2 mm). CONTROLLED BRAKING: Features V-shaped friction grooves with asymmetrical lateral channels that adapt the friction to the rope type for better control during lowering or rappelling. LIGHTWEIGHT & DURABLE: Minimalist aluminum construction weighs only 57g; rounded rope slots reduce wear on the device and the rope.
