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. Thin desert tips corner? 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. Funky pin scars? The X4's embedded cam springs allow for an ultra-narrow head width that fits in those tight spots other cams won't. Awkward horizontal placements? Thanks to super-durable aluminum protection beads, the X4's cable withstands repeated abrasion without compromising flexibility. Pumped out of your mind and ten feet out from your last piece? 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

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 4.8 out of 5 by 10 reviewers.
Rated 5 out of 5 by Amazing !!! Great Cams!!! easy to use triggers and they fit EVERYWHERE. Double up on the 1's and .75's. March 5, 2014
Rated 5 out of 5 by 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. January 3, 2014
Rated 5 out of 5 by Everything you would want in a cam After hearing about the X4's, I was really looking forward to giving them a try. I got the opportunity to use each of them at Red Rocks last weekend. They are everything that you would want in a cam. November 15, 2013
Rated 5 out of 5 by 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! November 3, 2013
Rated 5 out of 5 by 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. August 2, 2013
Rated 5 out of 5 by Excellent Cams These cams are a great addition to the already sterling lineup of C3 and C4 cams produced by BD. Their narrow head-width works incredibly well in pods and inconsistent cracks and the armored stem is perfect for horizontal cracks. I've also found them to be less bulky on my harness compared to the C3 and C4 (near) equivalents. I've been very pleased thus far and I'm looking forward to getting a few more to fill out my rack!

Rated 5 out of 5 by The Next Evolution in Cams I've been waiting patiently for Black Diamond to tackle the super flexible stem challenge and they've done it. Best of all, they clearly didn't rush. From the moment you pick up an X4 you realize it is superior to the competitors. The trigger action is perfect, no buckling when you're pumped, great camming range and the narrow head width slots well for unique placements. June 25, 2013
Rated 4 out of 5 by Rock for the aid and thin gear. I have climbed on the x4's for aid and loved them. They are a must have for any aid rack. They protect super well in horizontal placements. The flexible stem gave me confidence to high step even when the stem was totally flexed. I also loved the super small x4 cams. The stacked axles gave them a range that made them super useful. I highly recomend this cam for any thin crack. The head width on the x4 cams is as narrow as any 3 lobe cams I have on my rack. May 31, 2013
