Camp Ball Nuts
Camp Ball Nuts (previously known as Lowe Balls) have a unique design, which makes use of the principle of opposing wedges to give protection in thin parallel cracks where nothing else can be placed. A sliding ball pushes against a grooved wedge when weighted and the system provides enough protection against low fall factor falls. Ball nuts will protect fissures as small as 3mm while maintaining a breaking strength of 8 kN.
p>Being thinner than cams, ball nuts will protect smaller fissures. The design of these nuts also ensures that they make more contact with the rock that standard cams.
