ABSTRACT:
The object of this invention is to provide a sash balance foot seal mechanism for sealing the space between each side of a window sash and the adjacent window jamb or jamb liner.
Each sash balance foot seal mechanism has a foot seal comprising a flat resilient member into which the ends of a metal catch member are embedded. The catch member secures the foot seal to the sash balance mechanism. Each foot seal has a depending projection for sealing a complementary slot in each side of the sash. Each foot seal further has a low friction seal coating at least on the surface slidably engaging the jamb or jamb liner.
