I'm sure the big wigs did their homework before they introduced this service. The guys at the top are very well informed about other company's services and operations. I find it very hard to believe that OD would be ignorant enough to violate a copyright law. More than likely the patent has expired or OD found some loop hole. And by the way there is no company that supplies OD with the dividers, they're homemade. Simple ply-wood, 2 by 4's, and the same deck bars that the deck trailers come equipped with. The only thing special they do is paint the deck bars red and stencil the words security divider, or something to that affect.
