This ball nut is the smallest and lightest active protection in the world. It works in the smallest of cracks and is rated to 8kN. Each nut comes in a color-coded size for fast identification when you need to place gear in a hurry. The narrow depth of these nuts fit shallow cracks better than traditional camming devices (friends). A must for the serious trad climber.
