CAMP Ballnut

Unlike traditional spring-loaded camming devices that rely on rotation, Ballnuts use a sliding ball mechanism to expand against the rock. This design allows them to fit into extremely thin, parallel-sided cracks where standard cams are too bulky or cannot engage properly.

Ballnuts are highly effective in thin, hard rock fissures, but they require clean, parallel cracks to function safely. They are not recommended for soft or friable rock, as the concentrated force of the sliding ball can damage the rock surface.

The 2:1 expansion ratio provides a versatile range of placement options within a single unit. This means you can cover a wider variety of crack widths with fewer pieces on your harness, which is critical when weight and space are at a premium on technical routes.

The CAMP Ballnut system covers a total range of 3 to 18 mm across five sizes. If you are climbing routes known for thin, technical seams, it is best to carry the full set to ensure you have the correct size for the specific crack width you encounter.

Yes, an 8 kN rating is standard for this type of specialized thin-crack protection. While it is lower than some larger cams, it is designed specifically for placements where no other gear will fit, offering essential security in otherwise unprotectable terrain.
