A sash lifter for positioning a window sash within a window frame of a casement window includes a body portion presenting a sash positioning surface. As the window sash is rotated within the window frame about an axis of rotation defined by at least one hinge assembly, the window sash encounters the sash lifter and rides along the sash positioning surface until it is properly situated within the window frame. The sash lifter may include a barrier structure extending transverse to the axis of rotation to facilitate positioning of the sash lifter within a track of the hinge assembly. The sash lifter may also include a tail structure extending outward from the body portion for increased forced-entry resistance. |
