To be used in a vertical blind assembly, a carrier assembly including a plurality of carrier members, each member having a carrier frame with an axial bore extending therethrough, a transverse gear track tangentially disposed beneath the axial bore and a generally C-shaped attachment member perpendicularly disposed along a lower edge of the carrier frame, and a stem member having a vane holder portion and a drive gear rotatably disposed within the generally C-shaped attachment member. The vane holder portion and the drive gear portion being interconnected with one another such that each is independently rotatable and the vane holder portion is further adapted to have a limited range of rotation relative to the drive gear, thereby enabling complete alignment of all vanes. The carrier assembly further includes an axial pinion rod extending through the axial bore of each of the carrier members so as to engage a first set of gear teeth disposed along a top edge of a horizontal rack gear slidably positioned within the transverse gear track of the carrier frame. The horizontal rack gear is prevented from vertically tilting within the gear track upon rotation of the pinion rod by a protruding ridge along a rear face thereof which is slidably disposed within an elongate groove in the transverse gear track, thereby assuring that movement is fluid and uninterrupted.
