CAMP Ball Nut is a specialised active protection device designed primarily for very thin and shallow cracks where conventional cams are too large and passive nuts may be difficult to place securely. The smallest Ball Nut can be used in cracks starting at approximately 3 mm.

The Ball Nut uses a unique sliding metal ball and wedge-shaped body. When correctly placed and loaded, the interaction between these components creates a camming action that allows protection in exceptionally thin parallel-sided cracks.

A major advantage is its shallow placement depth. Ball Nuts can also work in shallow cracks, pin scars and certain small flares where even modern micro cams may not fit. This makes them particularly useful for trad climbing, aid climbing and demanding crack routes.

Ball Nuts are available in five colour-coded sizes for fast identification while climbing. Together, the complete range covers exceptionally thin cracks from approximately 3 to 18 mm.

Sizes:

• #1 – range 3–6 mm, weight 31 g, strength 8 kN
• #2 – range 4.5–9 mm, weight 40 g, strength 8 kN
• #3 – range 6–12 mm, weight 49 g, strength 8 kN
• #4 – range 8–14 mm, weight 59 g, strength 8 kN
• #5 – range 10.5–18 mm, weight 74 g, strength 8 kN

Key features:

• active protection for exceptionally thin cracks
• ideal for parallel-sided and shallow placements
• fits placements where conventional cams are too large
• very shallow placement depth
• five colour-coded sizes
• complete range from 3 to 18 mm
• compact and lightweight construction
• EN 12276 and UIAA 125 certification

Best use: trad climbing, aid climbing, demanding crack climbing and protection of exceptionally thin or shallow cracks.
