The NeverRust 72 in. Double Shower Rod in Chrome features two parallel bars that effectively double the capacity of a standard shower rod. Using two rods allows for a decorative shower curtain on one rod and a protective shower liner on the other. Or if desired, use the second bar to hang towels or clothes. The rod is made of strong, lightweight and guaranteed rustproof aluminum. The rod uses the innovative TwistTight tension system, allowing fast and secure installation with no drilling, no damage to walls and no tools needed. Or, mount the rod permanently to walls using the included hardware. The rod adjusts to fit most standard shower spaces, ranging from 44 in. to 72 in. Limited Lifetime Warranty.
