Installation Notes

Installation is performed by carpenters, millwork installers, or general contractors during door hanging or hardware replacement. Power down any electric strike or access control hardware integrated into the door frame before servicing hinges. Use a sharp chisel and router to maintain clean mortise dimensions when replacing existing hinges. Verify door and frame prep depth matches the hinge leaf thickness before final fastening.
