I'll take a pic to show you. seriously, you can't tell at all that its clipped and its solid as a rock after that.

ah yes these work like a charm at the back wall panels HD, but Ive also reinforced the floor to wall connection with blu tack - works really well Now I can play with the set and not fear of an "earthquake" effect going to happen when I do fiddle with it heheheh
