The Black Diamond Oval Carabiner is a standard carabiner for big wall climbing. Oval in shape because circles just won't do, and it'll help prevent shifting. Available in two colors, polished or black, maybe you could get a few of each for color coding, or just for making a fun pattern on your harness rack.
