Use Versailles' Double-Up series to instantly create a double rod with ANY existing flat bracket rod set already mounted on your wall! Easy, no tool installation, and goes up in seconds. The patent pending custom end-mount support finial is specifically designed to create a continuous back rod by lining up Double-Up between multiple brackets to attach to your existing flat bracket drapery rod. Simply extend the rod between existing support brackets and use the hex screw (Allen key included) to secure the rod to the existing bracket. (One (1) Double-Up rod required for 28in to 48in rods; Two (2) Double-Up rods required for 48in to 144in rods). No brackets are included. Use with your existing rods.
