摘要
Disclosed is a design for a frame structure for fixing a viewing window of a fire door. The disclosed perspective window fixing frame structure is to provide a fire door perspective window with improved aesthetics as well as improved marketability by allowing it to be fixed to form the same plane as the front and rear panels without protruding from the front and rear panels of the fire door.
