Agreed about the U-bolt style.I edited the photo above to show how it works. It acts as a lever. Red is the fulcrum point, yellow is the adjustment bolt exerting downward force, green is the pressure point exerting upward force. In the picture above it, in the previous post, you can see the shank being forced upward in to the top of the receiver. This puts all the tongue weight/pressure on the area marked in green.
The U-Bolt style anti-rattle work the opposite. They pull the shank down in to the bottom of the receiver.
But I am not understanding this flat plate style of rattle reducer. It seems like it could reduce the rattle for a little while until it breaks. See in my edited photo below...
My yellow and green lines are obviously working against each other; thus making the fulcrum point My red lined area.
So this "anti-rattle device" is pulling a lot of weight down on that thin metal bar and pushing back up against the shank to do so. This is basically just twisting the shank upward on one side and downward on the other to torque it into the user thinking it won't rattle. I bet they get a lot of breakages at the blue line locations.
