Abstract: A hanger pin for a vertical vane covering for an architectural opening includes a new and improved symmetric headrail having uniquely designed carriers for suspending individual vanes wherein the carriers are designed to minimize skewing relative to a tilt rod as they are moved along the headrail. A pantograph system is utilized to interconnect the carriers, and is connected to the carriers in alignment with the tilt rod so as to minimize skewing. The carriers have pockets formed therein through which the traverse cord extends so that the traverse cord, which moves the carriers along the tilt rod, is secured to a lead carrier closely adjacent to the tilt rod to, again, minimize skewing. Light blocking rails are also attachable to the headrail to substantially bridge the gap between the headrail and the top of the suspended vanes to prevent light from passing therebetween. The tilt rod is keyed to gears in the carriers to facilitate assembly of the control system with all vanes properly aligned.
