What is a common use of a coupling link in rigging?

A coupling link is primarily utilized in rigging to hold two components together securely. In rigging operations, it serves as a connecting element that links various components, such as chains, ropes, or other hardware, ensuring that they work in unison. The integrity and strength of the coupling link is crucial for maintaining the stability of loads being lifted or moved.

While tension adjustment and flexibility are important aspects of rigging, they are typically managed by other components or techniques, such as tensioning devices or specific rigging knots. Measuring weight involves scale devices that are separate from the role of a coupling link. Therefore, the primary function of a coupling link is to create a secure connection, justifying its correct identification as the option related to holding two components together.
