The front and rear sidepieces of the ladders are connected to front and rear horizontal runs of a tilt cord at eyelets which are spaced along the horizontal runs. The tilt and lift cords are connected to individual spool members of a cord-operating unit. The blind is adapted to be combined with a window having metal framing and, where the window has spaced glazings, the ladder-and-slat assembly is adapted to be located between the glazings. The spool members of the operating unit are adapted to be located in a channel of the window framing.
