The Black Diamond MiniWire Carabiner offers a superior function for your next climbing adventure. The lightweight construction means you don't have an unnecessary load weighing you down. The innovative design that includes the optimized nose geometry, allows you to quickly clip and unclip for a speedier climb. The D-shaped carabiner is designed so that more weight is borne by the stronger hot-forged spine and not the side with the clip. Having the right carabiner is important for your safety. Trust your security to the proven Black Diamond brand.
