Which statement best describes inline loading compatibility for shackles?

• A. They Are Suitable for Side Loading
• B. They Must Be Used for Non-Linear Loads
• C. They Are for Inline Loading Only
• D. They Should Be Anchored With Rope

Answer: (C)

Inline loading compatibility means the load is applied along the shackle’s pin axis, so the force runs straight through the bow and pin and the rated capacity is valid. When a load is directed from the side, it creates bending and reduces the effective strength, increasing the risk of deformation or failure. Therefore, shackles are designed for inline loading only. Side loading isn’t appropriate, the concept of non-linear loads isn’t the standard description for shackles, and anchoring with rope isn’t how shackles are intended to be used.
