The Sigma is a versatile D-shaped carabiner designed for secure and reliable use in various climbing situations including belays and personal anchor systems. Its design proves particularly efficient in quickdraw setups to clip the rope, providing assurance against the involuntary opening of the carabiner in the event of a fall on a challenging pitch with heightened risk of falling.

Enhanced with a state-of-the-art Twin-Gate wire-gate system, it allows for swift and safe operation without the need for additional maneuvers such as screwing, thus offering a clear advantage over other systems in terms of safety and speed. This innovative system significantly reduces the chances of accidental openings, which might occur due to rock contact, incorrect rope passage, or involuntary hand pressure, while also offering heightened resistance owing to its dual opening feature.

Built to last, the Sigma carabiner retains its functionality even in the harshest conditions, resisting elements like dust, earth, and ice that often compromise other systems. Its gate-wire combination is designed for easy handling, facilitating use with gloves and ensuring simple attachment to all types of devices, including brakes. Moreover, for enhanced safety and reliability, each unit is individually tested and laser-marked with the testing date and a unique progressive number. This diligent approach ensures that the Sigma carabiner stands as a benchmark of quality and safety in climbing gear.
