Intuitive belay device with reliable blocking of the climbing rope. The first generation of the Smart belay device was successfully launched in 2009. Built on the experience the new Smart 2.0 offers significantly improved braking effectiveness as well as optimized geometry and intuitive handling.


Operating the Smart 2.0 is very simple, as it works without moving parts or levers. At only 80 g, it is lightweight and sits perfectly in the hand.In the event of a fall, the Smart 2.0 reliably blocks the climbing rope.  


As it operates according to the tube principle, it's suitable for both lead climbing and top rope climbing.


The safety carabiner interacts with the newly developed high-performance break insert. The pros: More security and optimum support for the belayer. When the climber takes a break, the effort required from the belayer is reduced by the already blocked rope.
