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.

Comments about Black Diamond C4 Camalots:

These cams are the best! Easily retractable lobes makes placements quick and simple. Never fear the gear when you have a solid camalot placement protecting your fall. Plus the aluminum jingle from your waist belt brings a feeling of joy. Best cams on the market.


Durable, and catch you when you fall.

By Matthew

from Chapel Hill, NC

Comments about Black Diamond C4 Camalots:

What else do you want? They are easy to place, and you can be confident (if placed right and in good rock) that they'll catch you. I love my set of Camalots. I'll never buy a different brand of cam.

Still the best

By Phillip

from Sisters, OR 97759, USA

Comments about Black Diamond C4 Camalots:

Over the years I have been glad to see more and more entries into the SLCD market. Despite the variety of different options out there the BD Camalots still stand out above the rest. They are a great balance between price, expansion range, weight, and do all this while maintaining superb quality. These are the smoothest cams I have used and a good placement with any one of these inspires confidence. Still pricey but worth it.


Just keep getting better and better.

Comments about Black Diamond C4 Camalots:

I've been using Camalots ever since they came out. The first ones were great and they just keep getting better.

Go with industry standard

By Thomas

from Germany

Comments about Black Diamond C4 Camalots:

I don't need to say it but I thought I would anyway. these things are the best out there. They are the industry standard and everyone know it so why buy any other cam that has not been put to the test like the Camalot has? Everything works flawlessly, and when you can get one of these in a crack you can sigh in relief knowing your set.

Camalot C4s are the bee's knees

By Scott

from Colorado

Comments about Black Diamond C4 Camalots:

Purchased a couple extra C4's to compliment my trad rack. Love and trust camalots! I have taken falls on a number of different sizes and they have always performed great. Highly recommended.

Smooth trigger, easy to place, easy to clean...and they work!

By Coby

from New Hampshire

Comments about Black Diamond C4 Camalots:

BD cams are the only cams I trust! I especially like the time tested Camalot. I have taken several unexpected leader falls on these guys and they have always held! The trigger is smooth, the cams are easy to place and they are easy for a second to clean. I truly believe that these cams are the gold standard!

It's already stuck!

By Joseph

from Bellingham, WA, USA

Comments about Black Diamond C4 Camalots:

I've only owned my new number three for a week and it's already fixed on a route. "What should I do I can't get it out dad?" Golly gee wiz it, I think to myself. I just bought two more number three Camelots. "Just climb Jacob I'll just have to buy two more." You see that's my policy. Every time I loose one, break one, or get a number three Camelot stuck, I just have to replace it with two more.

Comments about Black Diamond C4 Camalots:

I go through at least 1 full set of cams each year. I use them in the desert and on the granite. The cables eventually wear out and break, the plastic stems eventually crack and prevent the cam from working but overall no other cam works better. So if you use and abuse them like me, expect to buy lots of them. If you rarely use them and keep them out of the desert, they will give you more years than mine! Rob Pizem


The best cams

By Nicholas

from Big Sky, MT, USA

Comments about Black Diamond C4 Camalots:

These are hands down the best standard cams out there. The double axle allows for increased range which is very important. The sizes overlap pretty well with only a few exceptions which only really matter in Wingate sandstone. Camalots are generally pretty easy to place and remove due to the trigger action whereas some cams have a tendency to get stuck or walk more easily into poor placements. DMM made dragon cams to copy the C4 but the dragon cams have a much shorter stem which makes removal more difficult. In anything but a shallow placement this will make the cam more difficult to remove and more likely to be irretrievable. As is advertised, "the gold standard for camming units." I couldn't say it better myself. For smaller cracks I like to supplement my rack with some small offset cams and C3's. Additionally, you can be sure that BD will back all of their products, an attribute that is becoming rare in the industry.
