Hah! hook friends. Needs a flat wall and screws only protruding the barest minimum amount. 100% movement free on two of mine so it is possible, but the third in our bullshit porch is against some awful lumpy paint render finish thing and just slumps sadly. It was improved after relentless fettling but not as good as the others.
