The Roman Series of professional hinges is able to accommodate 3/8 to 1/2 inch (10 to 12 millimeter) glass. A variety of five styles, including Wall Mount and Glass-to-Glass types, gives design flexibility. The Offset Back Plate allows for a clean sight line from the shower exterior. They are made of solid brass with all moving parts (pins and springs) in stainless steel. Roman Hinges are self-centering, and contain a Reversible 5º Pivot Pin.
