Why We Like The Black Diamond Camalot C4

Lighter and more convenient than ever before, the Black Diamond Camalot C4 brings the muscle without the heft. Coming in 10% lighter than its predecessor, this iteration saves grams without losing strength and maintains the same camming angle and placement ranges we have come to depend on. Giving the larger sizes stiffer stems, Black Diamond has uniformed flex across the line, so the 6 no longer feels wobblier than the 0.3.


  • Best-selling cam with a lighter, more modern design
  • Same camming angle and placement ranges as the previous C4
  • Lighter more sculpted lobes for optimal strength-weight ratio
  • Bi-color slings differentiate small and large cams of similar color
  • Sizes 4, 5, and 6 cams have trigger keepers to reduce racking volume
  • Single stem and double axle design doubles as cam stops
  • Large thumb loop provides a clip-in point for aid climbing
  • Sling tags tucked under shorter bar-tack for a cleaner look
  • Item #BLD00Z8

BD makes the best cams for trad!

I recently got a whole set of BD c4 cams and have loved them! I have a couple sets of other brands and seem to have the best of luck setting these C4s. Would definitely recommend!

Camalot C4

The black Diamond Camalot is my favorite camming device for protecting traditional rock climbs. I am interested on climbing in Yosemite where this device can be useful.

Sold my Ultralights for this.

The Ultralights are excellent cams. But with my recent entry into family life I'm not getting out much and the lifespan of the Ultralights didn't make sense anymore. Honestly the C4 lineup isn't that much heavier. Especially when incsider where they came from when I started climbing 35 years ago. The new C4 lineup is dreamy.

Goldilocks Cam

Love the balance and feel. As sturdy as it needs to be without adding a lot of extra weight.

It's a Black Diamond cam-a-lot.

It's a Black Diamond cam-a-lot. Its awesome. For you super climbers out there, this is when name actually makes a difference. Its not a pair of sweatpants, its your protection....

#4...more like #1

There's a reason the camalot has become the default size marker in climbing. And BD continues to innovate. The new trigger keepers are an ingenious way to solve a problem not readily apparent on the surface. Glad to see the Camalot continue to push the envelope. Looking forward to placing this bad Larry.
