Abstract
An operating control system for a retractable shade including a roller reversibly rotatable within a headrail includes a clamp system for gripping an endless operating cord in a neutral position to prevent rotation of the roller and a tensioner if properly mounted in a fixed position will release the clamp system to permit rotation of the roller while positioning the runs of the endless cord in a closely spaced relationship to minimize the risk of an infant or child becoming entangled in the cord.
