Well suited for use in belaying and organization of the work position. Large size to allow anchoring of several ropes. Wide opening to allow clipping of large diameter bars. Pear shape is particularly suited to belaying: facilitates the reversal of an Italian (Munter) hitch. Triact automatic locking system (metallic sleeve): easy to operate, even with gloves. Rapid unlocking with two movements. Keylock system: snag-free body / gate interface, avoids accidental snagging of the carabiner onto the anchor, the rope, the harness.
