Does anyone know where to obtain locks that fit on the metal track at the bottom of noticeboards with sliding glass in front? Not mega high security, just to restrict access to the contents. From distant memory, about 2cm x 2cm x 1cm with a keyhole in the front. I know of locks for glass with holes drilled at the centre, to prevent the panes sliding open past each other, but the glass isn't drilled in this case.
