Eagles and spears are the two most popular finials (toppers) for indoor and parade flag sets. The Flag Code of the United States does not address the use of finials on poles but traditionally the eagle is used on the poles with the US flag. Spears and other ornaments are used for other categories of flags. These finials all come in either as ABS Styrene Plastic material or Vacuum Plated Aluminum. Each is tailored to your preference for your flag set.
