C-Hooks used with electric scaffolds must have what feature?

• A. Threaded nut
• B. Rubber grommet
• C. Solid or welded suspension eye
• D. Adjustable chain

Answer: (C)

When suspending electric scaffolds, the connection point between the hook and the scaffold must be a single, permanent load-path. A solid or welded suspension eye provides that continuous, non-detachable connection that can handle dynamic loads without loosening or failing. Threaded nuts can back off under vibration, rubber grommets don’t supply the necessary strength and can wear out, and adjustable chains can slip or change length, creating instability. So the required feature is a solid or welded suspension eye.
