Adjustable Glass Railing Stiffeners are high-quality glass components made from durable 2205 stainless steel and feature a brushed satin finish. These stiffeners are used to connect two panels of glass together and can be adjusted between 90°-180° to accommodate the glass railing requirements of your application. Stiffeners are suitable for high-pressure, highly corrosive environments and are for use with 13.52-15mm glass. Plastic inserts are provided to keep glass from making direct contact with metal stiffeners.
