The LiteForge Screwgate Carabiner is Black Diamond's lightest locker, and this 3-Pack can complete any climber's anchor system. You can use all three and only a climbing rope to create an anchor for yourself and a belay station for your second, or you can add a sling or two to make a standard anchor station. Despite packing small and feeling weightless, each carabiner's nose is wide enough to accept clove hitches.
