Secures tight to the wall or tub.
What I like most about this product is that it is very sturdy and grips very well.  The only thing that I would say negative about this product is that when you set the bar in place if you have it a little off there is a a little tab on the suction part to pull on to release the suction but the little tab is so small that you really can't get ahold of it.  But the suction and the grip locks down very securely.  Ib would buy again.
