Our Windscale Banner Bracket hardware is used for installing custom banners on street poles. One bracket is used at the top and bottom of each banner. The Windscale 8 Banner Bracket Casting uses a 3/4″ diameter fiberglass rod and two stainless steel bands, making for a quick banner hardware installation. Our sign and banner hardware is graded using the Beaufort Wind Force Scale. Rated at Windscale 8, this banner bracket casting can withstand winds up to 46 mph. Windscale Banner Bracket hardware is manufactured using aluminum casting and black powder-coating.
