The CRL Estate Series of professional hinges is able to accommodate 3/8 to 1/2 inch (10 to 12 millimeter) tempered safety glass. A variety of four styles, including Wall Mount and Glass-to-Glass types, gives design flexibility and allows the designer/installer to create custom enclosures limited only by their imagination. These beautifully finished, solid brass forged Estate Hinges make it possible to mount 3/8 to 1/2 inch (10 to 12 millimeter) thick shower doors without surrounding frames, so the door has an almost "floating" appearance. The Estates heavy- duty stainless steel springs allow the door to swing 90 degrees inwards and outwards. A friction cam allows the door to be firmly maintained in any position, except when within 15 degrees of the closed position, where it is tapered to assist in centering the door. Using two hinges with 3/8 or 1/2 inch glass (10 or 12 millimeters) the hinge will hold up to 80 pounds (36 kilograms) with a maximum width of 28 inches (711 millimeters). Using three hinges with 3/8 or 1/2 inch glass (10 or 12 millimeters) the hinge will hold up to 120 pounds (54 kilograms) with a maximum width of 34 inches (864 millimeters).Specifications:Glass Thickness: 3/8 to 1/2 inch (10 to 12 millimeter) Tempered Safety GlassConstruction: Solid BrassHinge Swings: 90 Degrees Inwards and Outwards Closing Type: Self-Centering when within 15 Degrees of closed positionCut-Out RequiredIncludes: One Hinge, Gaskets, Screws and Template Custom finishes are available on request.
