The Black Diamond Camalot C4 #5 is the purple cam, covering 85.4 to 148.5 mm and rated at 14 kN. At 348 grams it is a heavy piece to carry, and you carry it because nothing smaller will protect a crack this size.

• Colour code and range: Purple, 85.4 to 148.5 mm, wide hands through to offwidth.
• Rated strength: 14 kN rated strength.
• 348 g: the price of protecting big cracks, which is why most racks carry one rather than two.
• Double axle design: the feature that gives Camalots their wide expansion range compared with a single axle cam.
• C4 rather than Ultralight: the standard C4 is heavier but more durable and considerably cheaper than the Ultralight range.
• Origin: Made in the USA.
