Black Diamond Camalot C4
Black DiamondCamalot C4

Gold standard camming device.

There are many reasons why most climbers rely on Black Diamond's Camalot C4 to save them when they fall. Just look around world-class climbing destinations like Yosemite and Indian Creek, and you're bound to see trad racks filled with Camalots. That's because this best-selling and most-trusted camming device boasts the original double axle design for an unparalleled performance. Double axles provide a larger placement range to give you more opportunities to place each cam in cracks ranging from offwidths to tight fingers. The double axle design also allows you to place the cam passively like a stopper. The Camalot also features a continuous cable stem for strength, an ergonomic thumb loop for easy handling, Black Diamond's patented sling for long-lasting durability, and a trigger with stops for easy cleaning.

Bomber pro as the kids say

  • Familiarity: I've put it through the wringer

C4s are the backbone of many a trad climber's rack, and they are rightly so. I love the expansion range the double axle design gives the cams, I love the durability of these bomber pieces, and I love the simplicity of their design. Such a well designed invention, no wonder they are a tried and true staple of the cam industry!

These are some of the best all around cams. Learned to climb with these cams and have owned them for years. I need to resling a few through Black Diamond but after that they'll basically be new again!

If you're looking for a solid, easy-to-use, convenient and color-coordinated trad rack, start here. These cams are sturdy and strong, can be used tons of times and then still continue to work exactly how they're supposed to. I lead my first 10+ the other day and relied on mainly 2s and 3s to get me up in, despite my few hangdogs on these cams. Felt safe the whole time, even in sketchy situations. I'd recommend this pro to anyone.

  • Familiarity: I've used it several times

Took my first ever fall on gear last week. My foot slipped unexpectedly and while in mid-fall I realized like I never had before that I wasn't on bolts anymore. After being caught I looked up in horror, not quite ready to accept that I was still alive and well, until I saw my #3 still right where I had placed it. These things hold like champs and inspire confidence. I anticipate taking more falls on the c4's in the future and trust that they'll continue to keep me alive. I'd recommend them to anyone.

BD C4 cams

  • Familiarity: I've put it through the wringer

Feedback from relative: "Great, durable product from a trusted company. They are light and easy to place and to retrieve. No complaints come to mind when I think of Black Diamond cams and I will be purchasing many more to complete my trad rack."

139th five star review!

    I think that the volume of positive feedback speaks to the C4s quality.
    There are other cams that are better suited to specific placements/ different rock types but I don't think that there are any with a double axle design that span such a wide range of crack sizes.

    Easy to recommend

    • Familiarity: I've put it through the wringer

    There is no better camset for the price.

    Superb Gear, Competition Catching Up Tho

    • Familiarity: I've put it through the wringer

    I started my rack with Camalots years ago and keep coming back. In most ranges they are a superb pieces, and the massive range of the whole set means you can keep one cam type from splitters to off-widths cracks. I have been recently impressed though by the updated Master cams which appear in superior in many ways, but I simply won't be replacing all the BD's because of it. In sized larger than 4, check out the Technical Friends instead. They are wider and have better stability.
    Black Diamond has major competition these days and needs to reinvent these (and I don't mean by charging outrageous prices for the UL's)



      Golden Standard

      • Familiarity: I've used it several times

      I finally decided to buy my own cams after my partner (who has cams) moved to different city. I could have bought Black Diamond Ultralight, but I didn't want to spend extra $130 (or more) to shave off 239g.

      BTW, I just wanted to say BackCountry, you guys are awesome for going extra mile and being flexible to work with my unique situation.

      Light weight and durable

      • Familiarity: I've used it several times

      This is my go to cam. Great features and light weight easy to carry.

      Climbing Cam

        Great cam and light weight easy to carry. Very fair price.

        Heavy, but durable

        • Familiarity: I've used it several times

        BD camalot C4 are heavier cams but durable and have great features. They will be my go too.

        Thrift Shop

        • Familiarity: I've put it through the wringer

        I'm gonna drop some cams only got 20 stoppers on my harness. I I'm climbin' lookin' just to go up, this is fucking awesome. Walkin' up the climb like wuddup I gotta big Camalot. I'm so pumped up off some cams I got at the gear shop, sand in the gears it's so damn dusty, people like "damn, that's a well-used cam D." Pluggin' em hella deep, rollin to Yosemite, Lycra's all pink cept my shoes, them's are green.

        What else is there to say?

        • Familiarity: I've put it through the wringer

        All the other reviews have summed it up. The classic cam. It performs flawlessly and has never let me down.

        I mean cmon

        • Familiarity: I've put it through the wringer

        Silly to review such a tried and true piece of gear but it does exactly what you need it to do... keep you from decking. Easy to plug easy to clean no frills, I often double with my partner who has DMM and I always seem to have a harder time cleaning and plugging his pro.


        • Familiarity: I've put it through the wringer

        There's a reason that Black Diamond Camalots are the gold standard for cams. They plug better, clean easier, and are easier to handle than most other out there. Other cams are great, but everyone should know what a Camalot feels like. Picked up another .3 to round out the rack, couldn't be happier.
