Camp USA Core Belay Lock
Best anti cross loading carabiner for safety conscious climbers.
This HMS carabiner solves the most common belay anxiety by physically forcing your rope into the correct position. The captive inner gate eliminates the risk of dangerous cross-loading, though the added mechanism makes it slightly bulkier than a stripped-down, traditional carabiner.
