French doors and combination frames are usually fitted with a full length double glazed unit or divided with a midrail set at a height of 850mm with either glass top and bottom or a plain or moulded half panel in the bottom. All doors are supplied with toughened safety glass. French doors can open in or out. Open out doors are fitted with door restrictors to prevent the doors from being blown about when in the open position. Locking handles are fitted to both doors.
