If hinges are to be used for other than their intended purpose, approval must be obtained from the CRL Shower Door Technical Sales Department. Use only the template included with this hinge. Cut-out dimensions for CRL hinges may not match those of other brands. Please note that the Bellagio hinges are delivered without determining the zero position. After installing the hinges please set the zero position and tighten both screws.
