I need some advice hanging some shelves on a plasterboard wall... The shelves are in the kitchen and will be holding around 30kg of kitchen guff like plates, pots/pans etc.
I've discovered that the plasterboard to which I need to fix the shelves is sitting about 20mm away from the masonry. I initially was going to use some molly 40kg rated expanding anchors but these are about 50mm long. The shorter ones are only rated at 10kg.
So what are my options for anchor bolts that can be installed in narrow spaces?
I've just been reading about springloaded toggle bolts, but worried that the toggle 'arms' won't have enough space between the plasterboard and masonry to expand fully when inserted...
