To boxes to combine my devil (1kg the piece) with the wall bracket, I M5 / M4 screw (not supplied) used. Simply screw head as a hanger take the threads of the screw through the hole of the wall mount and finished the whole thing. Then I have the boxes thanks to the Kugelgelänks the wall bracket set and finished the whole thing was.
This was my first home theater boxes and installation went smoothly!
So I can only say good :)
