1 x FIXINGS. 2 x FISCHER PLASTERBOARD FIXINGS + SCREWS. THREADED - Can be screwed into timber or wall using a raw plug. ANCHOR PLUG - (Fischer) For masonry walls, 12mm drill and setting tool needed. Even though the radiators are free standing in our opinion - and not just a sales ploy - wall stays are really an essential item to fit, as the radiators are heavy and you would not want a radiator to be falling on anyone.
