CRL Glass Hinge Brackets are designed for use on 'all-glass' partitions or fireplace screens made of 3/8" to 1/2" (10 to 12 mm) thick glass. The highly polished chrome or brass finish complements most modern decors. Concealed set screws secure the glass. This is a Non-Load Bearing Type Hinge. The hinge is not designed to support the weight of the glass or mirror. The weight must be supported by the floor, counter or other means.
