How to Install an In-Ground Flagpole

To affix the truck (the flanged top that holds the finial and through which the halyards are threaded), set the double sheave into a notch on the top of the pole, so a sheave with the halyard pulled through lines up with a cleat on the base. Before screwing on the truck, coat the inside and edges with silicone caulking for a watertight seal. Fit the finial into a ½-inch threaded hole in the center of the truck.
