Modeer Shackles are narrow, elongated shackles used for handling of what?

• A. Rope
• B. Stud link chain
• C. Anchor chain
• D. Life lines

Answer: (B)

This question tests matching the rigging gear to the shape of what you’re handling. Modeer shackles are designed with a narrow, elongated profile that fits the unique geometry of stud-link chain. The studs on stud-link chain raise the links and create a profile that a bulky, standard shackle can’t seat against properly. A slender, long shackle can pass between links and bite securely, allowing safe lifting, connecting, and handling of the chain without bending or damaging the links. Rope and life lines use different hardware and gripping methods, so they aren’t suited to these shackles. While anchor chain is a form of chain, the specific design here is tailored for stud-link chain handling, making it the best choice.
