Which component connects multiple rigging components together and usually uses a removable pin?

• A. Hook design
• B. Link
• C. Eyebolt
• D. Shackle

Answer: (D)

Shackle. Shackles provide a simple, strong connection point that lets you join several rigging pieces—slings, chains, and hooks—by opening the removable pin, threading the parts together, and reseating the pin. This design makes it quick to assemble or adjust in the field while keeping a secure load path when the pin is in place. The other components aren’t primarily used to connect multiple rigging pieces with a removable pin: a hook is for grabbing the load, a basic link is a simple connector that doesn’t emphasize a removable pin in the same way, and an eyebolt is for attaching to a single lifting point in a threaded hole. Always use the correct size and rated working load limit for shackles, and ensure the pin is fully seated.
