A revolutionary rope clamp for its extremely tiny dimensions (only 125g) and ergonomic shape. Its small size allows the users hand to sit comfortably inside the device, close to the rope in the same way as you would grabbing the actual rope. Available in right and left versions. The best support to ascend a rope with the "ROPE WALKING SYSTEM" (as if climbing a ladder). After testing the system, cavers confirm an excellent performance and a 30%-efficiency's increase during the ascent.
