I had hollow / drywall walls in my old house (it was an older house that had an extra layer built inwards, if that makes any sense), and figuring out what to use was a bit of a pain. But, I managed to hang up some pretty heavy stuff on there.<p>The one thing was a kitchen cabinet with a fold-out door that would carry all my plates and the like - 30+ kilos? Up to 50? And since it's ikea stuff, it only needed two screws at the top!<p>I tried plugs that look like the self-drilling anchors described in the article, they ended up taking out a big chunk of the wall, whoops. We settled on the plastic butterfly anchors (number 1 on the picture), which held up just fine - but I did live in constant fear that the wall would give in.
