The sawtooth hanger is welded to the back securely but seems totally inadequate for a 10 pound ornament we had hoped to hang outside above garage doors.  If a wind gust should hit and the ornament fall, someone could be badly hurt, and the ornament certainly ruined.  The piece is beautiful, but we're struggling to find a secure way to hang it.  A bigger screw to go through siding is too large for the sawtooth grooves.
