What does "plumb" mean in the context of rigging?

In rigging, the term "plumb" refers specifically to ensuring that components are perfectly vertical or aligned. This concept is crucial in various rigging applications, as vertical alignment impacts not just the aesthetic presentation of the setup but also its safety and functionality. When rigging structures, checking that elements are plumb allows for loads to be evenly distributed and prevents excess stress on any individual component.

Correctly indicating that a component is plumb often involves using a plumb line or a level to verify the vertical alignment. This ensures that loads are not only secure but also balanced, which can significantly affect the overall performance of the rigging system. Maintaining plumb alignment can prevent issues such as uneven wear, potential failures, or shifts that could disrupt safety or cause accidents during lifting or suspension activities.
