Mammut Crag Key Lock Carabiner

The keylock nose eliminates the hook found on traditional carabiners, which prevents the gate from snagging on your rope, gear loops, or bolts. This makes clipping and unclipping significantly smoother and faster.

Yes, it is specifically optimized for sport climbing. Its straight gate and robust construction make it an excellent choice for the bolt-end of a quickdraw or for leading routes where ease of clipping is a priority.

At 47 grams, this carabiner strikes a solid balance between durability and weight. It is light enough to keep your rack manageable on long sport routes without sacrificing the strength needed for repeated falls.

While you can use it for those applications, it is designed primarily for sport climbing. If you are looking to shave weight for alpine or trad, you might prefer a wire-gate carabiner, but this model offers superior durability and ease of handling for cragging.

The major axis strength of 24 kN indicates the carabiner's maximum load capacity when closed and loaded along its strongest spine. The 8 kN ratings for open gate and minor axis strength provide a safety margin, ensuring the carabiner remains reliable even if the gate is accidentally bumped or loaded incorrectly.
