Fixed the dryer reliably

Our dryer is on a waist-high shelf which is mounted on the wall. I was a little afraid that the dryer could maneuver down by the vibrations.
These fixing plates but that's not an issue. The dryer has no chance to slip, since the plates are glued and are additionally fixed by the weight of the dryer.
At first I had doubts and wanted to settle span the dryer with an additional Spanngut, but that has become redundant, since the panels are easily enough.
