What is the significance of a 100% efficiency rating for rigging components?

A 100% efficiency rating for rigging components signifies that there is no loss of strength in the component when it is loaded. This means that the component can fully utilize its rated capacity without any factors (such as friction or deformation) that would reduce its effectiveness. In practical terms, it indicates that the rigging component can handle the maximum specified load without any reduction in its lifting capability, which is critical for safety and performance in rigging applications.

Understanding the concept of efficiency is essential in rigging, as it directly affects how riggers assess the safety margins and working loads of rigging systems. If a component is rated at 100% efficiency, it assures users that the component will perform as expected under load.
