This device is a Fehlkonstuktion. The attachment to the wall does not take place, as usual, in the middle of the device, but on the right, yellow plastic part. For this 3 filigree screws with 4mm plugs are included. How this is to keep in a wall wall, do not open up to me. To use much larger bolts is also not possible due to the very small and even recessed mounting holes. When it still creates a lot of luck, in the wall to install the dowel so that the lamp depends theoretically horizontally (a game of chance), so you will be taught by tightening the screws of the better, because the lamp depends then, due to the weight , left down. Who designed such crap?
