Part of what makes the Walker Picture Hanging System so popular is the ability to create a customized art display system. A wide variety of components are available to create a display that suits the space, the available light and the artwork itself. This low-profile hanging system can be expanded by using rod connectors to join two or more lengths of rod. The end result is a display system that is strong and durable, and can be reconfigured to accommodate changing display needs. Best of all, the system is understated, allowing the art itself to stand out and garner the attention of those who view it. The rod connector will fit any of the rods available within the Walker system, but is best suited for steel or fiberglass rods. .
