This Geneva 90 Degrees Glass-to-Glass Shower Door Hinge replaces the old style Geneva Series 90 Degrees Glass-to-Glass Hinge which required a cut-out in both the shower door and the fixed panel. This new style requires only two holes (per hinge) in the fixed panel, and a cut-out in the shower door. These professional shower door hinges are able to accommodate 5/16 to 1/2 inch (8 to 12 millimeter) tempered glass and are available in a variety of finishes.
