I have the background system fitted with three 3,70m x 11m paper roll to a plasterboard ceiling. The wall / ceiling mounts are each provided with 2 holes for screws at the ends. For mounting on plasterboard with cavity wall plugs the holes are m. E. too close together, so I was afraid that there is not enough stability in the Rigsplatte remains when I use both holes. Therefore, I have put a screw at each end and in addition drilled in the ceiling mounts centrally between the hooks each another hole. So I could fasten each bracket with four screws. As anchors Fischer hollow wall anchors have used metal, which spread widely over the sheetrock (the exact name I have unfortunately not more) that there is but in any well-stocked hardware store.
The whole maintains itself with the three major roles bombproof - more coming all the sheetrock down.
