This carabiner automatically closes with the help of magnetism, thus ensuring a high level of safety. The magnetised locking clamps at the opening are drawn together by a steel insert in the nose of the carabiner, making this mechanism a powerful companion for a wide range of climbing operations. In order to open the carabiner lock, both locking arms must be pressed at the same time so as to overcome the magnetic force between the snap-lock and the stainless steel insert.
