A pivot bar for a double hung window sash includes an elongated member having a knobbed end for engaging a window jamb or frame. The pivot bar has vertical and horizontal shields for completely covering the first and second apertures formed in the window sash. The pivot bar is “snap-fitted” into the first and second apertures which are formed with a conventional electric drill. The first aperture formed in the side of the sash is less than a complete circle in order for the drill bit to simultaneously form the second aperture in the bottom of the sash.
