If a D shackle cannot be used to support multiple slings, what type of shackle could be used?

• A. Screw pin shackle
• B. Bow shackle
• C. Quick-release shackle
• D. Rigid shackle

Answer: (B)

When you need to attach more than one sling to a single point, the inside space where the slings sit matters as much as the load rating. A bow shackle has a wider, curved interior opening compared to a D-shaped shackle. That extra width lets two or more sling legs lie side by side without crowding, which helps the load distribute more evenly and prevents slings from pinching or binding against the pin as you rig or lift. Other shackle types don’t offer that same clearance. A screw-pin shackle is essentially a D shape with a threaded pin, so it shares the same limited interior width and isn’t ideal for multiple slings. A quick-release shackle is designed for fast disconnection and can have extra hardware that reduces usable space and can introduce potential failure points under heavy rigging. A rigid shackle lacks the geometry that provides extra interior room, making it harder to seat multiple slings securely. So, bow shackles are the best choice when you need to support multiple slings.
