摘要： A plastic draw track for drapes which is extruded integrally with a valance. Also moulded plastic drape carriers which are formed with four domed projections on the underside for engagement with the track, thus reducing friction. A support bracket may be provided which enables the track to be carried from a wall or window frame in those cases where the upper edge of the window opening is below ceiling level.
