SWMBO has purchased a 4'X3' oak-framed mirror and wants it to hang on a plaster board wall. It weighs 20Kg. The mirror has two mounting brackets on the back which I would describe as a rectangular steel plate screwed to the back of the mirror with a D-shaped 'buckle' hanging off it (apologies, can't find it on Screwfix site to get its proper name). Can I put two large screws with spring toggles, or similar, into the wall and just suspend the mirror off those?
thanks, Paul.
