Since their introduction in 1987, Black Diamond Camalots have undergone three generations of refinement, while continuously proving themselves as trusted partners on the racks of climbers worldwide. Their patented double-axle design created a range of placement and strength unequaled by any other camming device—critical advantages that are still preferred 17 years later. BD has developed a technology in their head designs and cable stems, offering the greatest opportunity for solid placements by utilizing a larger expansion range. Significantly lighter weights than past cams, better flexibility and smooth action make the C4 Camalots the best protection available. *Due to safety and hygiene concerns, this product cannot be returned or exchanged.
