What must be displayed on the data plate of an adjustable brace regarding its WLL?

• A. Color coding for weight
• B. WLL at maximum and minimum extension
• C. Instructions for use
• D. Material type

Answer: (B)

The display of the Working Load Limit (WLL) on the data plate of an adjustable brace is crucial for ensuring safe rigging practices. Including the WLL at both maximum and minimum extension provides users with essential information necessary for making informed decisions about the load that can safely be supported at different brace lengths. This is particularly important because an adjustable brace's strength can vary based on its length; therefore, knowing the limits at various extensions helps prevent overloading and potential failures.

By incorporating these specific WLL values, users can confidently determine how much weight the brace can handle under varying conditions, which is vital for maintaining safety in rigging operations. This feature also aids in compliance with industry standards and regulations, as it ensures that users are equipped with the necessary information to operate the rigging equipment safely across different scenarios.
