The patent-pending Flag Pole Weight Anchors are a must for every guard member. Easily lock your existing carriage bolts into the flag pole and feel secure knowing they won't fly out. The weight anchors secure the carriage bolts into the middle of the pole so you'll never hear the rattle or clank of the bolts when you catch the pole. The Flag Pole Weight Anchors are made of brass with a rubber O-ring and hold a 7/16" carriage bolt. To adjust the weight of your flag pole simply unscrew the old carriage bolt, then screw in a different length bolt. You no longer need to tape your bolts!
