How many anchor points are required to rig a rappel lane?

In rappelling, the number of anchor points required is crucial for safety and stability. Utilizing three anchor points provides a balance between redundancy and security. The rationale behind this is that each anchor contributes to the overall strength of the system. With three points, you ensure that if one anchor fails, the remaining anchors can still support the weight of the individual rappelling. This three-point system allows for better load distribution and minimizes the risk of an accident due to a single point of failure.

While fewer anchor points, like two, might seem adequate in some contexts, they do not provide the same level of security that comes with three. More than three anchor points, such as four or five, can add unnecessary complexity and weight to the setup without significant benefits in most situations, as three is often regarded as the optimal number for achieving both safety and manageability during rappelling activities.
