DMM A847ANSI

The ANSI certification indicates that this carabiner meets specific, rigorous safety standards required for professional working-at-height applications. It ensures the hardware has been tested to handle the higher safety margins often demanded in industrial or rescue environments.

The D-shape is engineered to shift the majority of the load onto the carabiner's spine, which is its strongest point. This geometry maximizes the major axis strength, ensuring the carabiner performs reliably under heavy tension.

The Locksafe mechanism is a triple-action gate that requires three distinct movements—slide, twist, and pull—to open. This design significantly reduces the risk of accidental opening while you are working or climbing.

Yes, the keylock nose eliminates the 'hook' found on traditional carabiners, preventing the gate from snagging on ropes, slings, or bolt hangers. It makes clipping and unclipping much smoother and faster.

While it is built to meet industrial ANSI standards, its D-shape and high strength make it a very capable, robust option for climbing and via ferrata. However, keep in mind that it is heavier and more specialized than standard lightweight recreational carabiners.
