Ensure the door and frame are properly mortised to accept the square corner leaf before fastening. Follow applicable building codes and door hardware manufacturer specifications for fastener type and hinge count per door height and weight. Do not install on fire-rated door assemblies unless the hinge has been tested and listed for that application.
