The Mainstays Adjustable Heavy Duty Double Curtain Rod is a great solution for updating and layering the drapes, curtains, or sheers throughout your home. This double curtain rod is made of heavy duty steel and can be adjusted from 28 to 48 inches (71 cm to 122 cm) in length to accommodate your window. Using a double rod allows you to layer curtains and sheers over your window giving you better control over how much light to let into your room. The back rod has a 2 inch (5 cm) clearance from the wall and is great for sheers, while the front rod has a 3 inch (7.6 cm) clearance from the wall and is better suited for decorative curtains.
