Rustproof your bath and add more elbow room in your shower with Zenna Home's NeverRust Double Tension Curved Shower Curtain Rod. Constructed from aluminum, these rods are guaranteed for life against rust. The curve of this rod provides up to 9 inches of addition elbow room (when extended to 72") giving your shower a more spacious feel. Use the second rod to prevent mildew by separating the liner and curtain, or hang towels or clothes. Easy no-cut, telescoping design installs in standard 60-inch or larger 72-inch tubs, but fits in spaces as small as 50 inches. The patented TwistTight installation is quick and easy - simply extend and twist. Not only is aluminum a rust-free metal, but it also weighs less, making installation easier than typical steel rods. Our shower rods works with all standard shower curtains and adjust to fit tub openings from 50 to 72 Inch. Step-by-step instructions are included with every rod.
