The CRL Riviera Wall Mount Hinge (handed left or right as viewed from outside the shower) will self-close from approximately 60 degrees, and will hold open at 90 degrees. As the door opens, the hinge lifts the glass so the sweep will not bind at the bottom. Being a gravity type hinge, the weight of the door assists with the self-closing feature. An attractive flush mount fastener is on the rear of the hinge, and the mounting screws are concealed. Made of solid brass and stocked in two finishes. Holes are required in the glass. Riviera Hinges accommodate 3/8" and 5/16" (10 and 8 mm) thick tempered safety glass.
