The Grivel Master Pro Belay is a hard-wearing and versatile belay device designed for safe and efficient use. It can be used for belaying and rappelling, and also functions in guide mode as a self-locking plate to belay a second climber. Its design minimizes force transmitted to anchors and reduces wear on the rope over time. The device features side holes to reduce weight and dissipate heat, preventing the rope from overheating. Using gloves is recommended for enhanced braking safety. It is suitable for single-pitch, multi-pitch, and classic wall climbing.
