Technical Notice

Declaration of Conformity




SIRIUS lies perfectly in your hand. The auto-returning operating lever has a particularly small radius of motion so that you can work fast, accurately, more comfortably and safely. During rope insertion, which is intuitive and simple, the carabiner on the harness can stay connected to the device. We designed the route of the rope in such a way that it is protected from twisting and kinking, and from excessive wear and tear. SIRIUS was developed for extended use under the toughest of conditions. That’s why it is made of up to 100 % metal – without any vulnerable synthetic spots. SIRIUS.
