The French doors can be installed as two different size panels with the narrow one
being passive (used only when wider opening is required) and the wider one as the
main panel (used regularly) or as a matching pair where one or both panels can open
full swing either into the room or out toward a terrace or garden for easy access. The
inward opening French doors are used in rooms where space is not limited. A pair of
French doors does not include a fixed central mullion, allowing for a wider
unobstructed opening.
