The world’s best selling and most-trusted camming device, the Camalot features a double-axle design that offers unparalleled performance.

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)

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.

Great cams, particularly in the larger sizes

24 December 2013
These cams set the standard that all other cams are compared against. The cams have a stable 4-lobe design, huge expansion range thanks to the double axle, and a flexible single stem. I don't particularly care for the two smallest sizes, as they have a relatively wide head that keeps them out of many placements. I use Mastercams for the small sizes, and C4's from size 0.5 to 5.

Excellent all round cams

Solid camming action, good range and sturdy construction makes these my favorite cams. Pretty much the standard in cams for ages - what more could you want?
