Door apparatus and a method for installing the same in a door opening of a building
 A frame-and-door unit includes a frame structure and a door. A first vertical frame of the frame structure is supported on one side portion of the door by hinges. When the door is closed, a second vertical frame of the frame structure is supported on the other side portion of the door by a latch bolt and a strike. The unit is bound tight with a band that extends across the door. Each of the vertical frames is formed having a band groove along which the band is passed. The unit, kept bound tight with the band, is fitted into a door opening of a building. The band is cut after the vertical frames are fixed to the edge of the door opening. The cut band is then removed from between the edge of door opening and the vertical frames.
