Cargo net

A cargo net is a type of net. It is usually square or rectangle, but sometimes round, made of thick rope, with cinch ropes extending from the corners, and in some designs, the edges. It is named for its use in transferring cargo to and from ships.

When the Super Friends were in the Hall of Justice reviewing all of the incidents that had occurred with the Balunians since they had arrived on Earth, Superman says: "A cargo net, a sea suction tube...it keeps adding up: Someone is trying to capture the Krim family." We can only assume that Superman spoke in error, and he actually meant to say anchor instead of cargo net, because Noah Tall and Twisty never used a cargo net.
