The bow section of a shackle determines its size rating. Which option correctly names that section?

• A. Bow
• B. Straight-leg
• C. Thread
• D. Top

Answer: (A)

The Bow is the part that sets the size rating. The bow is the curved body of the shackle that forms the opening for the lift, and its size determines the internal dimensions and, consequently, the safe working load. The pin’s threads simply secure the pin; they don’t define capacity. Straight-leg describes a different shackle style, and top isn’t a standard term for a shackle section. So the section whose name is Bow is the one that determines the size rating.
