I have one of those bars. It's pneumatic I think. You position it and then work a handle that slowly pumps it out. When you deliver you press a button that lets the pressure off. I'd use it use it at the back side to keep freight from tipping backward. It didn't have to take nearly as high loads that way, usually none at all.
Yeah...that makes sense, using it that way. Somewhere in another thread about a year ago Turtle or someone was saying they're good load bars but not so good for Sprinter walls, as they are easily pushed out and deformed. Place the ends onto load spreading ribs or existing e-track would lessen that, I would think.
