What is the primary purpose of a master link in rigging?

The primary purpose of a master link in rigging is to connect slings and hardware. A master link serves as a central point where multiple connections can be made, allowing for a secure and effective way to attach various components such as slings, hooks, and other rigging hardware. This connection is essential for distributing the load evenly and maintaining stability during lifting operations.

Additionally, the selection of a master link must account for the load being lifted and ensure it meets safety standards, as it can significantly affect the overall rigging system's integrity. In contrast, other options like increasing load capacity or stabilizing the load focus on different aspects of rigging and are not the primary function of a master link. Moreover, reducing friction is more related to the design of the rigging components rather than the role of the master link itself.
