Utilizing a double-axle design to allow for a better way to retract the cam lobes, the Black Diamond Camalot C4 cams have a larger expansion range than other products featuring the traditional single-axle cams.


This product has a large expansion range providing increased overlapping between sizes. This allows someone to carry less pieces and still cover all the necessary bases for proper climbing.

In addition, the cams have a continuous cable stem C-loop that is stronger and more durable than comparable products. This allows for the Black Diamond to maintain its flexibility in the coldest weather and still is capable of easy placement due to its rigid stem.

Using gloved hands, the ergonomically-designed trigger permits a climber to manipulate the cams easily and individually.

To make matters better, when a climber finds him or herself on soft rock, distribution of the load is easily accomplished due to the wide cam lobes. Likewise, the overall width of the product is narrow, meaning that placement in shallow cracks is more easily accomplished.


Black Diamond wasn’t just satisfied with a strong product, the company also focuses on identification by color coding the sewn-on nylon sling and cam lobes.


This product as reviewed is available in 10 sizes.

    By far, this is the best cam you can find on the market today. Whether you need to add a quality piece to your rack or you simply are looking to start a new one, the camalot is far and away your best choice in camming devices. Personally, I’ve faced some major challenges on certain climbs, but the Black Diamond Camalot gives me some piece of mind no matter how dangerous it gets.
