Abstract: A simulated structural gasket for supporting a panel, such as a glass window panel, within an opening defined by a window frame. The simulated gasket includes two elongated members which may be extruded aluminum, extending along and engaging opposite sides of a building frame flange which surrounds the window opening. The elongated members project beyond the frame flange into the opening and accommodate on edge of the glass window panel between them. A cross-member projects from one elongated member toward the other and overlies the frame flange. The cross-member and other elongated member are interlocked to prevent movement of the elongated members away from each other. A layer of resilient, rubber-like, material covers the outer surface of each elongated member and has a gasket portion located between its respective elongated member and the glass panel.
