CRL Roman Series 90 Degree Glass-to-Glass Clamps have two versatile applications. They can be used to connect two fixed panels of glass at 90 degree, or by utilizing the wood screw that is included, as a shelf bracket or offset wall mounting clamp. They have rounded corners for a "softer" look. The Clamp has an open back so the glass can either be mitered or overlapped. Clamps are designed for use with 5/16" or 3/8" (8 or 10 mm) thick glass. A hole is required in the glass for installation. By utilizing the wood screw that is included, the clamp can be used as a shelf bracket or offset wall mounting clamp. Custom finishes are available on request. For more information contact CRL Shower Door Technical Sales Department.
