So I purchased this and when I get it out of the box I realize it does not use the thule locking core feature. I should have looked at this closer in the store, but I didn't.
Is there a good way to lock these down that does not look bad?
more permanent Perhaps this is a rather blunt way of making the unit permanent but put a M6 nut on the end of the bolts after you tighten the thumbscrews and dab it with crazy glue. Tighten the nut a little more so the glue is in the threads. It’ll definitely be a pain to take off.
