The gold standard for camming units, Black Diamond Camalots' double-axle design allows retraction of larger cam lobes, giving them a much larger expansion range than traditional single-axle units. They are lightweight, the cable loop and trigger are easy to grab, and our patented slings are large enough to manipulate with gloves. Accept no substitutes.

  • Double-axle design offers widest range for each cam unit
  • C-Loop continuous cable stem design is strong and durable
  • Color-coded for easy identification and wide range of sizes
  • Neutrino Rackpack available for easy racking (see Carabiner section)

Cam Comparison Chart

Our range of Camalots is designed to provide protection across the full spectrum of crack sizes, from small incipient seams, to perfect hands, to full-on offwidths. Camalots, Camalot C3s and Camalot X4s each have their own unique advantages, and a well-rounded rack will likely contain some or all sizes of each cam. Check out the chart to see how the members of the Camalot family overlap.

Rated 4.9 out of 5 by 25 reviewers.
Rated 5 out of 5 by Yup, "The Gold Standard" BD Calls these the "Gold Standard" for camming units, and they're right. For my guiding and personal climbing it is what people are most familiar with. Durable, light, trustworthy, wide expansion range...the C4 has it all. The only competition they have on my rack is from BD's own X4 in the .5 size. August 14, 2014
Rated 5 out of 5 by The Standard I have used my rack for 3 years and they have not had any issues. I love the quality and ease of use. I would recommend them to anyone. Even a Pro from another company told me in a clinic to get these over his sponsors brand. no brainer July 30, 2014
Rated 5 out of 5 by Range and Motion Obviously the increased range of the double axle is a huge selling point of these cams. When first learning to place trad gear this greater expansion range makes the learning curve a little less steep. I also just appreciate having a little more "wiggle room" when I am at the end of a pitch needing to build an anchor and only have a few pieces of gear left on my harness. The trigger motion is also incredibly smooth compared to some other SLCDs on the market. July 24, 2014
Rated 5 out of 5 by The Standard I've falled on these cams quite a few times and never been disappointed. When I look around at other climbers, these are the cams their rack is full of. July 7, 2014
Rated 5 out of 5 by Truly the gold standard These are the best cams by far. All other cams are either a copy or inferior. February 8, 2014
Rated 5 out of 5 by Great cam Great all round cams they are cheap, easy to use, and robust there is not much else on my rack then them the only problem with them is the none flexible stem January 5, 2014
Rated 5 out of 5 by There should only be BD cams! These are far and away the best cams on the market. They are so easy to place and bomber if placed properly. Just place it, clip in and move on, start worrying about your next moves. It's gotten to the point that I started thinking about crack sizes as according to the BD cam color scheme. The fact that they made biners to match the cams makes it that much easier to grab and go. November 19, 2013
Rated 5 out of 5 by Seriously, no rating needed they remain the gold standard These are simply the best all around cams. The thump loop/ clip in point is a great feature and the action remains firm but not too stiff across lots of use. Keep them cleaned and oiled and they will last year in and year out. For 90% of climbing you don't need anything different. Weird pockets and pin scars may call for a specialty piece. As a climbing instructor I look around and few of my peers have anything different for their workhorse pieces. November 1, 2013
