Petzl Attache 3D Carabiner The Petzl Attache 3D Carabiner is a new version of the classic Petzl Attache carabiner that is 37 percent lighter. We found the Attache to be a little smoother for belaying a second in auto-block mode. However, the Attache 3D is better in just about every other category. The key-lock gate is one of the smoothest to operate and has a special design to prevent over-tightening and locking up. It is incredibly smooth to belay with. Probably the world's best screw locks carabiner. You can see how much thought has gone into engineering this product. Good looks, light in weight and an absolute joy to handle, the red gate unlocked indication are a bonus. The rope bearing surfaces of the Petzl Attache 3D Carabiner have been optimized to balance fluidity with a minimum of excess weight.
