The Petzl AM'D Screw-Lock Carabiner is a D-shaped carabiner for connecting devices on harnesses. The shape and size of this carabiner makes it great for most uses, from connecting a belay device to your harness or as a connector at the end of a lanyard. The D-shape makes it one of the strongest and lightest locking carabiners Petzl makes.
- D-shape has the highest strength-to-weight ratio of all carabiner designs
- Keylock screwlock system
- Perfectly suited for use with belay devices due to its symmetric shape on both ends of the carabiner
