How do you attach the bracket to the wall?
Answer
Find your favorite position for the board on the wall in advance and mark the optimal attachment points.
Drill a 6 mm hole in the wall using a suitable drill.
Then insert the included dowels into the freshly drilled holes.
Now fix the board holders with the screws provided.
If necessary, a little fine-tuning, place the board on the brackets and you're done.
