Visit general retailers such as HomeDepot.com and BedBathandBeyond.com to find a selection of extra long tension rods. OrganizeIt.com and BedBathStore.com also feature a variety of tension rods for purchase.
Tension rods are designed to fit inside a window's frame or other enclosed area above the window. They function on a tension system; users adjust the rod's length until it fits snugly within the frame. Tension rods are durable enough to support lightweight curtains, and they are available for living room curtains and show curtains. No brackets are needed to support the rods, and extra-long rods are designed to fit in larger enclosed areas.
