Combining an incredible expansion range with a super-flexible cable stem and a narrow head width, the Camalot X4 is a super-versatile 4-cam unit for everything from big wall missions to hard, modern free climbs. Learn More


Combining unparalleled expansion range with single-stem flexibility and a narrow head width, the Black Diamond Camalot X4 represents the missing link in our gold-standard Camalot family. The smallest three sizes of the X4 feature our Stacked Axle Technology, which uses a unique machined axle to give more expansion range per size than any small four-cam unit on the market. In fact, the six sizes of the Camalot X4 cover the same range as eight sizes of comparable units. The X4's embedded cam springs allow for an ultra-narrow head width that fits in those tight spots other cams won't. Thanks to super-durable aluminum protection beads, the X4's cable withstands repeated abrasion without compromising flexibility. We also added a hot-forged trigger bar and symmetric swage to improve handling and eliminate buckling.

  • Double axle (.75, .5 and .4) and Stacked Axle Technology (.3, .2 and .1) provide huge expansion range
  • Narrower head width than original Camalot fits in more places than ever
  • Aluminum armor beads protect cable stem without compromising flexibility
  • Symmetric swage and hot-forged trigger bar eliminate buckling and provide ergonomic handling
  • Lightweight yet durable Dyneema sling for easy identification and differentiation from other Camalots
  • Oz, HoodWire and Neutrino rackpacks available for easy racking

cam comparison chart

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, Camalot X4s and Camalot Ultralights 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.

X4: The Missing Link in the Camalot Family

Camalot™ X4 is rated 4.8 out of 5 by 46.
Rated 5 out of 5 by from 2 Words: Flexible Stem Took a few of these (.3, .4, and .5) up to Turkey Rocks and loved them. Got into a hairy 11+ pitch that turned into an aid climb pretty fast. Had a few places of horizontal or near horizontal cracks where my other small cams, small C4s and C3s, just didn't feel secure. The flexible stem on the X4s in those cracks are just so money. They incorporate everything you already love about the C3s and C4s and they've made them better. You'd think with the flexible stem that the cam head would flop around when placing them. However, the pretty wire inside keeps the cam pretty stiff as you place it, and if you need that bend over a lip, it obliges perfectly. Can't wait to try the .1 and .2.

Rated 2 out of 5 by from Reduced effective range These cams are great because they have a narrower head than the Camalots. However, they have a tendency to get stuck much like Wild Country Friends. The lobes do not retract fully when the trigger has been maxed out however the lobes can be forced to retract further than the trigger can control. This results in the cam being able to walk in to placements much tighter than the trigger is able to release. As you probably know any cam can get stuck however these get stuck much easier than the C4's. This reduced trigger function also reduces the functional range of the camming device which is perhaps the greatest benefit of a double axle cam. If you compare a camalot next to an X4 you will understand what I am talking about. This all being said, I have the two smallest offset X4's and they do not share this issue so I love them! Camalots for life!

Rated 5 out of 5 by from Great device! I was climbing a route in RRG called "vector trouble." On this route, there is a section of very thin, nearly perfectly parallel crack. I was a couple of feet above my last piece and on a relatively thin section of rock. Rather than trying to slot a nut in, which would have taken around 1-3 minutes, I threw in a 0.2 X4, and was able to feel completely comfortable for the crux section of the climb. This new cam allowed for an easy and efficient transition from climbing, to placing pro, to launching back into sequence. I'm glad I had it!

Rated 5 out of 5 by from Good addition to the Camalot family! Recently decided to try out some X4s instead of another brand I was using in the small size range. Stacked them alongside my new ultralight Camalots and off I went for a couple of weeks cruising around Colorado (Lumpy Ridge, Garden of the Gods, Flatirons, etc.) I took a chance and didn't take the small cams I used to use. Fortunately I never missed them since these X4s did everything I asked of them. I found the .2, .3, .4, .5 the most useful of late. They are now a part of my standard Canadian Rockies rack when I anticipate a need for small gear. Super happy with their performance so far, especially in conjunction with my regular range of Camalots since they seamlessly extend the range into smaller crack sizes.

Rated 4 out of 5 by from Some sizes are incredible.... One is average, and one is dissapointing.... I absolutely LOVE the .1, .2, .4, .5 sizes. They are an incredible addition to my rack. The .4 might just be the best cam ever made! They fit anywhere, are easy to remove, and have a very narrow profile which makes them great in Zion (where I live and climb) and other desert climbing locations. The .3 size is good, but a .3 C4 has a double axle. The double axle makes for a great cam stop (which the small X4's don't have.... A lot has been written about the lack of cam stops on the small (.3-.1) X4's. I think that in sacrificing camstops they have made a more narrow profile, thus improving the X4 in pods and wonky placements. I absolutely HATE the .75 X4. It's head is too big for its stem. This causes it to flop around. Hard to place reliably on lead. The .75 C4 is way better. I would recommend buying a .5, .4, .2, .1 X4 rack with .75 and .3 C4's to complement them. They are a little more expensive, but are worth the price to add more depth to your rack. Overall an incredible family of cams with one black sheep that should be avoided and one good cam that just isn't as good as the equivalent C4.

Rated 5 out of 5 by from When you are reluctant to place a nut or stopper These come into their own when you are on what I call a nut eater crack. You know the kind, they always have a "permanent" piece someone had to leave behind. Or, you have to take a nut tool and something to hit it to get your own nuts free. When you don't want your second fumbling for what seams like hours, trying to extract a jammed nut. These cams replace all that. Yes there is a weight penalty but the speed and ease of use, can out weigh that. These cams are the best of the mini cam bunch.

Rated 5 out of 5 by from Trustworthy piece After reading many reviews and product details, hesitating on purchasing this new piece, I figured that BD hasn't really produced anything in the area of Climbing Hardware that I didn't like...this is true of the Camalot X4 line as well. Some people remarked that the larger pieces were too flimsy and more difficult to place, I'd have to say that I disagree. The 0.75 found it's mark every time in horizontal and vertical cracks. X4 is an awesome addition to the BD family of climbing protection.

Rated 5 out of 5 by from Flexible stems are awesome I love these for the ranges they cover and the flexible stems are awesome (esp. for horizontals). They seem easier to place in fiddly areas than C4s of the same size.
