The Double Banner Boulevard Bracket Kit is a state-of-the-art system designed to withstand the elements. The base is made of rust-free cast aluminum with fiberglass arms. The fiberglass arms flex in strong winds transferring some of the wind load off the banner. Stainless steel bands make installation easy. Double Banner Bracket Kits include 4 brackets, 4 fiberglass arms, 4 end caps, 4 pins, 4 rings, 4 40" stainless steel bands and 4 zip ties. Everything you need to secure two banners to a pole. Double Pole Banner Bracket Kits are available in 4 sizes. 18", 24", 30" and 36" fiberglass arms support most standard width banners. Double pole banner boulevard brackets can be adjusted to any length by simply moving them closer or further apart on the pole. 18" - Item 302021 24" - Item 302007 30" - Item 302009 36" - Item 302023*Mounting hardware not included
