How to Install an In-Ground Flagpole

Set the pole into the anchor and insert the pivot bolt. Adjust the pole until it is plumb, checking how it looks from afar as a helper holds it steady. Holding the preferred position, mark the pole at the predrilled holes on the anchor. Remove the pole, rest it on the padded sawhorses, and drill holes for the locking bolt.

Insert the pole into the anchor again and install the pivot bolt. Finally, install the locking bolt and finger tightn it. Once again, check to make sure the pole is plumb.
