These Trianon Series 90 Degree Glass-to-Glass Clamps have beveled edges with cut corners, and are designed to secure 1/4 to 5/16 inch (6 to 8 millimeter) glass panels together. Can also be used as a horizontal shelf clamp. Continuity of design is maintained by matching the look of the hinges used. They are available in several decorator finishes and are constructed of solid brass.
