Input:
At first use, this bar seems to be fairy sturdy and continuously adjustable (twist tightened threaded pole) as opposed to ratchet only type bars.  Though, like other bars it depends on rivets to hold on the sleeve that attaches to the rubber pad plates.  The failure of cheap rivets on a Keeper brand cargo bar (defective on arrival) caused me to return my order.  The Stoneman bar seems to be sturdier that the Keeper, but it still relies on rivets.  So, durability is uncertain.
