ATV Arizona Safety Flag with 5/16" White Pole and Mounting Hardware This is for one (1) NEW Arizona ATV Safety Whip Flag with Mounting Hardware. The flag is 12 x 18 inches long. The mounting bolt is 1/2" with lock washer, washer and nut. This is standard size. This flag can be used with or without the mounting bolt. Easy to pop off with a hammer if needed. The whip flag pole is a solid 1 piece 6 feet white pole ( 72 inches ) and 5/16" around in diameter. The flags are made out of a polyester blend material and are weather proof for outdoor use.
