A series of the many slats are joined together with hinges to form a sheet of slats that makes the shutter sheets/Door. On the upper side of the doors a small box holds the shutter when closed. Usually this box is visible but now a new installation pattern has been introduced to make it invisible inside the ceilings. Longer doors are used with motors to make it convenient for the use and shorter doors are used manual operated.
