Abstract
A spool forming part of a lift cord drum for a covering for an architectural opening has a generally cylindrical body about which the lift cord is adapted to be wrapped and a frustoconical end encouraging the wrapped cord to shift in a predetermined direction. A longitudinal slot in the cylindrical body retains one end of the lift cord and allows the end of the lift cord to slide along the slot as wrapped cord is increased or decreased so as to minimize the possibility of the cord becoming entangled in itself.
