Which item is used to attach tie-down straps to deck rails?

Explanation:
Shackles provide a secure, removable link to attach tie-down straps to deck rails. They are built as a U-shaped fitting with a threaded pin that locks into the other end, creating a strong connection to the rail’s anchor point. This setup distributes the securing force through a rated device, making it reliable for holding cargo in place without stressing the strap itself. The other options aren’t used for this purpose: a breakaway cable serves a different safety function, a stated weight like 3000 lb is just a rating rather than a connector, and WC-2 refers to a specific piece of equipment rather than the standard attachment method for deck rails.
