An extender for a combined double hung, double sash guide and weather strip unit is disclosed. The extender is slidably received in the open upper end of the parting bead of the weather strip unit and carries at its upper end prongs. When the extender is driven upwardly, as by raising the window sashes, the extender closes the air gap between the upper edge of the weather strip unit and the head jamb and at the same time the prongs are driven into the head jamb so that the extender also serves to attach the weather strip unit into the window frame thus eliminating the need for top staples or nails.
