ABSTRACT:
A headrail for a window blind is formed as an integral extrusion comprising a front valance and including rearwardly of the valance a first upward facing channel for receiving the pulley mechanism and a second downwardly facing channel for clamping the blind edge. A wall between the two channels extends upwardly beyond the channels and then rearwardly and downwardly to provide a flange whereby the headrail can be supported on a suitable hook member.
