Cross-loading your belay carabiner can be very dangerous, That is why Camp created the HMS Belay Lock carabiner that has an extra arm to make sure the carabiner stays where you put it. Feeding off of the main gate's spring, the secondary gate firmly spans the carabiner and secures itself into two dimples along the spine to anchor the orientation of the biner. The HMS shape gives you plenty of room across the top to handle a rope and tie off if needed.
