How do KBW brackets keep the banner from flying off or, stated another way, how does the banner stay on the fiberglass arm without sliding off?
This is very simple. Each banner should have a grommet installed near the top and bottom hems at the pole side. Our BannerFlex brackets are all provided with an eyelet on the arm or on the Main Casting (the JR). After the banner hem is installed over the fiberglass arm you apply a weather-resistant 18 gauge or heavier through the eyelet and banner hem and secure. It's that simple!
