The door and frame assembly consists of a frame with reversible uprights (5, 6) and a detachable transverse member (7). Hinges (14) have movable sections fitted to the door and fixed sections to the frame. To reverse the assembly, the frame transverse member is removed, the uprights are reversed, and the mobile hinge sections are adjusted along the door edge so that they engage with the fixed members. |
