The FUSE sets new standards for guided type fall arresters. Whether ascending or descending, the integrated centrifugal brake enables the device to move up/down the belay rope with incomparable ease from the very first meter. Furthermore, its ability, as a single device, to comply with all relevant European and international standards for large diameter ranges and the highest user loads coupled with its impressively compact design makes it the most versatile device in its class. The structural separation of the trigger and blocking mechanisms together with the lack of serrated jaws not only makes the device tamperproof and kind on ropes, but also enables it to be easily released from the rope after a fall. The mandatory combination with an appropriate DEFUSER shock absorber (S, L, or RESCUE) makes it possible to select a complete system that is ideal for the intended use thanks to the different lengths and performance parameters.
