Used for attaching tie down straps to deck rails?

• A. Breakaway Cable
• B. Conventional Bomb Chock
• C. Universal Munitions Chock
• D. Shackles

Answer: (D)

The main idea is that securing loads to a deck requires a strong, removable anchor point for tie-down straps. A shackle provides exactly that: a rugged U-shaped link with a removable pin that can be attached to deck rails or through lugs, giving a dependable point for the strap to go through or around. This setup resists the forces from load movement and ship motion, and the pin allows quick attaching or releasing when needed. That makes it the best fit for attaching tie-down straps to deck rails. The other items serve different roles: a breakaway cable is a safety device designed to release under certain loads rather than act as a strap anchor, and bomb or munitions chocks are used to prevent movement of munitions, not to provide anchor points for tie-down straps.
