You might have to snug the lock-nuts on the bar after a few times of use until its broken in. Theres plastic or teflon washers in between.
Otherwise you canreplace the lock-nuts withplastic knobs from your hardware store. If you get knobs, be sure they have metal threads and use lock washers to keep them tight. AllI had to do is snug the lock-nuts up a little bit and its been fine for me. I'm really happy with the stand so far. If you have any ????'sjust P.M. me. Happy Hunting!
