Which of the following is not a type of cargo restraint component in containers?

Draining channels are not classified as cargo restraint components in containers. Cargo restraint components are specifically designed to secure and immobilize cargo within a container, preventing movement that could lead to damage during transit.

Integrated horizontal rails, spring-loaded foot bolts, and load retainers are all examples of mechanisms that help to maintain the position of the cargo, effectively reducing the risk of shifting or toppling. Integrated horizontal rails serve as a track for securing cargo, while spring-loaded foot bolts can be used to lock down loads against the container walls or floor. Load retainers act as barriers that help keep products in place.

On the other hand, draining channels are features intended to facilitate the management of liquids or moisture that may accumulate within a container, rather than securing cargo. Their primary function is related to drainage and preventing water accumulation, rather than maintaining cargo stability during transport.
