A linkage arm is pivotally coupled at a first end of the arm by a first pivot at an intermediate location along a side member of the sash and at a second end of the arm by a second pivot at an intermediate location along a side member of the perimeter frame. One of the top pivot of the sash or the second pivot of the linkage arm is a sliding pivot that is longitudinally slidable along the side member of the frame. A biasing member exert a biasing force on the sliding pivot which retains the sash open.
