I put two Toggler cavity wall fixings (the type which are all plastic and open to a diamond shape) into plasterboard over a studded wall. I then tried to open them using the red rod tool supplied but without success. Had to resort to hammering in a nail - but then could not see if the nail opening the fixing or just drove through it. As far as I can tell the wall is normal thickness plasterboard with normal thickness coat of plaster.
Anyone else had this problem?
