This cargo securement device is placed on the exposed edge of an article to distribute tiedown forces over a larger area of cargo than the tiedown itself, to protect the tiedown and/or cargo from damage, and to allow the tiedown to slide freely when under tension.

• A. Dunnage
• B. Logistic straps
• C. Friction mats
• D. Edge protection

Answer: (D)

Edge protection is used when a tiedown rides over an exposed edge to keep both the strap and the cargo safe. It spreads the pulling force over a larger surface so the strap won’t be crushed or cut by the edge, protects the edge from sharp wear, and provides a smooth path so the strap can slide freely as tension is applied. Dunnage, which is used to fill gaps and stabilize cargo, isn’t placed on edges for protection. The straps themselves are the tiedown, not a protective device, and friction mats are meant to increase or manage friction in other ways rather than specifically protecting edges and allowing smooth strap movement.
