Many years ago, with small chldren, I fitted a hinged stair gate to the top of the stairs. It was metal and looked like the usual ones with vertical bars and pressure fixing points. However, instead of the pressure fitting, it had a hinge arrangement consisting of a thin metal bar that screwed to the wall and had two hinge points - one at the top and one at the bottom. The gate could be opened and closed just like a door and, and when not in use, could lie flat against the wall. Now, with small grandchildren, I need to fit another one but have been unable to source a supplier. Can anyone suggest one?
