A halyard is the rope that raises and lowers the flag. Internal halyards are quite simply halyards that have the working part running inside the pole. External halyards run outside the pole. Internal halyards generally have concealed access, often lockable, that makes flag theft more difficult by vandals. There is no such thing as a vandal proof flagpole, but internal halyards offer cost effective vandal resistance to varying degrees. The different methods of concealing access to the halyard determine the effectiveness of vandal resistance and how often your flagpole is used. The most effective is the flush fitting hatch cover, followed by the winch, the sliding collar, protruding cast aluminium cover and finally, the hinged door with key lock. Without doubt though, the winch is the easiest to use and because it is easy, it will be used.
