At first I was really excited by the hook. Unfortunately came up with my punching bag after a few blows against again.
The bolt with the joint and the punching bag attached to the ball bearing, simply slipped by far too small nut which is to keep the whole top.
The result is now a ceiling suspension in which the bolt is to keep everything has run out of thread.
I have the whole thing with some wire zusammengefrickelt so that keeps it very well now.
However, I would advise anyone to buy such a hook if he wants to hang a punching bag.
For lighter objects or if the holder is hardly loaded, you can certainly use it, but not even for a small punching bag.
Who wants to work safely and without frustration, but then I advise to invest some extra money and purchase a reasonable bracket.
