How are they secured to the rail?
Should I keep tightening the hex screw until they expand and lock?
I have done on one and it's still loose, I am afraid of cracking the weight or the rail if I tighten it more.
Thanks

Yes just tighten slowly until they lock.

Thanks :-)

Take em off, oil them, run tbe screws in and out a few times, and then put them back on. Things that dont move often get sticky and the stickyness makes you tbink you are over tightening them. Just clean em up ad begentle when you put them back on
