ABSTRACT:
A rattle free window having a sash balance that is provided with a sash hook that is connected to a slide by slot and pin means so arranged that the weight of the sash thereon cams the slide laterally against the window jamb. The sash balance may also include a novel clip which both fixes one end of the balance spring to its housing and also attaches the housing to the window jamb. The window may also include a ramp clip which automatically catches the slide when the sash is raised so that further raising of the sash can lift the sash off of the novel sash hook and slide structure.
