Incredible expansion range and low weight make the Black Diamond Camalot C4 Large Package a perfect way to beef up a regular rack. These three cams (size #4-6) cover the the largest sizes that Black Diamond offers, and expand a standard rack into the world of offwidths. Their thumbhole loop, wide trigger, and large expansion make the Camalot C4s easy to place when you need to fire in gear from a greasy finger stack. Their double-axle design also allows them to be placed as passive protection when nothing else is available. Rack your nice new cams right next to your trusty Stoppers. You'll be happy that you have them in about 40 feet.
