The D-shape makes it one of the strongest and lightest locking carabiners Petzl makes. Perfectly suited for use with belay devices due to its symmetric shape on both ends of the carabiner. In addition, the D-shape has the highest strength-to-weight ratio of all Petzl carabiner designs. This carabiner comes with Petzl's Keylock system.
