Extra light and easy to use - the Master Mono by Grivel! This single-tube device is designed for rope diameters between 7.3 and 11 mm, covering a wide range of ropes. As the Master Mono only supports single ropes, it is mostly used for sports climbing, indoor climbing and as a descender. It stands out for its extremely low weight, which is widely owed to material savings. These savings also reduce heat accumulation caused by the friction between the rope and the device. Moreover, they make the tuber easy to clean from ice and dirt. The supple handling of the device when it comes to belaying and abseiling is another major advantage. Ambitious sports climbers know that Grivels Master Mono highlights every set of equipment!
