I've had several generations of the Demco aluminum towbars, due to factory replacements. The 1st was an Aluminator had a separate tool to un-lock the slide couplers, the second had basically the same "tools" built into the outside of the bar, the third has the locks and levers acting internally. By far the third version (now called Dominator) is the best. I had failures of the "hinge" area on each of the 1st two tow-bars with welds and aluminum fracturing. Personally if it's not a machined block connecting to the pivot pin, I would not have it. I have towed 2 Ford Aerostar vans, a '96 Tracker, a 2003 Ford Sport Trac and now a 2014 Ford Flex with the Demco Aluminum towbars
