These internal halyard ground set aluminum flagpoles are cone tapered, and precision fabricated from new 6063-T6 tubing. They contain a winch system inside the flagpole shaft that can only be operated by a removable crank handle, thus protecting your flag from theft and vandalism. They taper approximately 1" every 5-1/2 feet. All poles up to 35' are shipped in one piece, and all poles 40' and longer are shipped in sections.
