This pole system allows your banner to be fully visible at all times. RotoArm® was designed and patented by Flags Unlimited. The horizontal arm rotates 360˚ around the pole reducing wind stress on the pole and preventing the banner from wrapping around it. The banner is sleeved at the side and top to go over both the vertical and horizontal poles. The Roto-Top fits all of our outdoor poles and the banner size is dependant on which pole you choose.
