To permit swinging movement of the door panel (2a) about vertical hinges (8) of a sliding door (2), suspended from hangers (13) running on a roller track (9, 19), without tilting or twisting of a vertical frame member (11) of the door, and in which a horizontal frame member (10) is secured to the hangers (13), a massive metallic angle (12) is inserted in the horizontal and vertical frame members and prestressed by engagement of a tension bolt (15) with the angle (12) in the horizontal frame element to provide a counteracting force on the vertical frame element (11) when the door panel (2a) is unhooked from the horizontal element (12) to permit swinging movement.
