A vertical blind having a head-rail, a plurality of carriers slidable in the head-rail for movement between open and closed positions. A respective vane is suspended from each of the carriers and a pivot rod is rotatably mounted in the head-rail and extending through the carriers for rotating the vanes. A control assembly comprises a controller securely affixed to a first carrier. The controller includes a control body slidably mounted in the head-rail, a first gear member disposed within the carrier body and rotationally coupled to the pivot rod and slidable thereon, and a control shaft rotatably mounted in the control body and extending through a base portion of the control body. The control shaft includes a second gear member operatively engaged with the first gear member, so that rotation of the control shaft causes rotation of the pivot rod via rotation of the second gear member and the first gear member. The control shaft further includes means for operatively coupling a wand to the control shaft, whereby the control shaft can be rotated by rotating the wand, and the control assembly can be slid within the head-rail by pulling the wand. The control shaft is mounted at an angle within the control body so that, when the vanes are rotated towards their closed position, the wand is concealed behind a vane suspended from the first carrier.
