The Exclusive Home Fetter wrap-around double curtain rod helps you achieve a "total blackout" experience-depending on your curtains' opacity-because it allows drapes to wrap around your window and sit flush with the wall so your window is completely covered. The adjustable curtain rod measures 1" diameter and can be used to hang various fabrics and curtain panels including grommet top curtain panels, drapes with rod pockets and back tabs. It can support heavier fabrics up to 25 lbs.
