What is the historical protective rating for a single point attachment using nuts and cams?

The historical protective rating for a single point attachment using nuts and cams is typically in the range of 5-10 kN. This range reflects the strength and reliability that traditional climbing gear, such as nuts and camming devices, can provide when used correctly in rock climbing and rescue scenarios.

Nuts and cams are designed to hold significant force, and their rated strength is based on testing standards and real-world usage. A rating of 5-10 kN indicates that under normal circumstances, the gear can handle this level of force, providing a reliable anchor point. This strength is crucial for safety in climbing and rescue operations, as it helps ensure that the equipment can withstand the loads encountered during a fall or when multiple forces are applied during a rescue.

Understanding this rating helps technicians and climbers make informed decisions about anchor systems, ensuring they use appropriately rated gear for the anticipated loads in a variety of situations.
