I've put up the pole 3X now and each time my daughter opens her curtains; crash! One bracket is fixed securely straight to the wall. The offending bracket has been fixed to expanding foam filler (as the hole in the plaster is large) using expandable screws, but still no joy. I want to avoid glueing a wooden baton as think this will just pull plaster away and also make the pole uneven. Also the screw hole size for the brackets is 6mm so can't use any larger screws. Any suggestions?????
