Abstract

Abstract This symmetrical corner connector is particularly useful for sliding door hardware and fastens on without screws or other connectors. Such a door has a panel having a G-shaped stile along each side and a U-shaped rail at the top and bottom, all of which engage the edges of the panel to form the structure of the door. The connector has a central channel for receiving a door suspension member and, on each side thereof, has a wing for engaging the back wall of the stile. An ear on each side of the connector near one end fits over the end of the stile to engage the interior thereof. A tang on each side near the opposite end of the connector fits through a slot in the stile and engages it in opposition to both the ear and wing. In addition, the tang has a spring clip for engaging the interior of the stile for preventing withdrawal of the tang. A hook extends over the top of the rail and through a slot to engage the front face of the panel.
