Abstract: An outrigger for mounting a dual-panel sign to a display system, the dual-panel sign having a first panel and a second panel positioned opposite the first panel. The outrigger includes a support end configured to be selectively coupled with the display system, an attachment end configured to be selectively coupled with the dual-panel sign between the first panel and the second panel, and an intermediate portion extending between the support end and the attachment end. The first panel and the second panel shield the attachment end from view. The support end, the attachment end, and the intermediate portion are each integrally formed of a rigid material. Sign assemblies and display systems provide additional advantages.
