This extremely compact and lightweight ascender is very rope-friendly because it has no teeth or cam. It operates by pivoting the rope around a lever when weighted. Simply open the rotating side plate, insert the rope and close the plate, clip a carabiner in the hole, and start climbing.

Standards:

- EN 12841/B for semi-static ropes ranging from 10 to 13 mm.
- EN 567 for semi-static and dynamic ropes ranging from 8 to 13 mm.
UPDATE 2024: maximum user's weight increased to 120 kg.
