sorry that you didn't catch the fact that I ask people to specify when they want the tow chain loops. Only about 20% do so I just leave them off for most hitches. They can be added afterwards easily enough. (PM me to discuss)
I've since updated my order process with a spiffy online form so that folks can't miss that step.
Bill, no wories. When I ordered I just wanted to carry the bikes, and it works great. It is possible I did see the hooks option and just ignored it. It has been awhile, I do not even remember when I ordered the hitch 2011 or 2012.
