For what it is worth. Posted by: Jackl on Mar-14-13 9:02 AM (EST)
You sound like a do-it yourselfer, so: I have Yakama bars with Thule J cradles. No matter what Thule says about them fitting round bars like Yakama; yes they will fit, but they will roll if you are pushing the boats on from the back or front. Problem solved by drilling a quarter inch hole through the bar and along with Thules clamp, I have the J cradles bolted with stainlees bolts washers and nuts that I can easily remove when I want to. You can also get innovative and save a bunch by getting various rollers and fittings at West Marine or a boating shop, and use L shaped brackets bolted to the bars. Jack L
