Your customers will appreciate this unique advertising system that acts like a moving billboard for highway-wide recognition of their products. Our Logomasters are screen-printed with fade-resistant UV inks on heavy-duty .026 aluminum panels. To display a logo, simply flip panels and lock the panels in place with the 4 stainless steel, spring-loaded fasteners that are double-riveted to the frame. The frame is constructed of extra-heavy .042 aluminum for lasting durability.
