The Black Diamond Camalot C4's double-axle design allows retraction of larger cam lobes, giving them a larger expansion range than traditional single-axle units. They are lightweight, the cable loop and trigger are easy to grab, and the slings are large enough to manipulate with gloves. Please note these cams are Cosmetic Seconds, or items that have a blemish that does not affect the performance or intended use of the product.
