The structure was not quite unkomliziert, and I also have the holes for the first grid 2-3mm too deeply set - as I have just kept the screens on the wall and drill holes have drawn. This allows you the door is not very high lift and the plastic feet always loops something. This has already inziwschen its mark on the marble behind (of course, not through the plastic, but as a grain of sand has then someday get caught ...).
The second grid I was a little more experienced in the attachment, it opens much easier, but also because I can now see small abrasion marks (in wood).
We have a Children baby taken from Vorbeseitzer - showing after 15 years no drag marks in marble (!) - But it also has roles.
Overall, one can say that the lattice work well, but I like to take the plastic feet real roles would have - even should the screws thicker the wall a number be (long enough they are).
