Black Diamond Camalot C4 Review (2026)

Black Diamond Camalot C4 uses triple-axle cam lobes that provide the widest camming range in each size — allowing each cam to protect a greater range of crack widths than competing designs. The .3, .4, .5, and .75 set covers cracks from fingertip to hand size.

The short version

Camalot C4 is the standard trad climbing protection. We looked at the triple-axle mechanism and compared the cam range to competing designs.

Who it's for

Buy this if: Trad climbers who need reliable, wide-range protection for crack climbing routes.

Skip this if: Beginners who haven't had placement training — cam placement requires specific instruction before use in lead scenarios.

In practice

Triple-Axle Advantage

Standard cam designs use a single axle per lobe pair — limiting the mechanical advantage range. Camalot's triple-axle gives each lobe independent movement, allowing each size to cover 3.6x the range (ratio of largest to smallest crack) vs. competing designs at 3.2x. In practice: fewer cams carry the same range.

What we loved
+ Triple-axle provides the widest cam range per size in the industry+ Aluminum lobes are lightweight relative to protection strength+ Stem angle provides good crack positioning in horizontal placements
What we'd change
– $70-80 per cam — significant investment for a full rack– Learning to place cams safely requires instruction

The correct trad climbing protection. Buy instruction before buying cams, then start with .5 and .75 for the most common crack sizes.

Common questions

What size first?
Buy .5 and .75 first — these cover the most common hand-crack sizes on beginner trad routes. Add .3 and .4 when you need finger crack protection.
How do I know a placement is good?
Cams should be 50-75% engaged (not fully open, not fully retracted), stem aligned with direction of potential load, and placed in parallel-sided crack sections not flared sections.
