I bought this thinking it would be a solution to stuff sliding ahead in the pickup bed. it's ok for this, but the ratchet steps are pretty course so it goes from not quite tight "enough" to pushing the sides of the box out in one click. the tube is about 1" in diameter so it has a good amount of flex in it. I wouldn't trust that it will stop anything of any mass from moving arround. am I happy with it, meh, not really, but am I unhappy enough to send it back... probably not...
