Upgrade and help rustproof your shower instantly with Zenna Home's NeverRust Aluminum Double Tension Shower Rod. The rod is guaranteed for life not to rust. And with two easy and secure mounting choices, you can select whichever installation method works best for your needs. Tension mounting allows for tool-free installation with no drilling and no damage to walls. Or choose permanent installation for secure mounting using the included screws and hardware. Instructions are included for easy-to-follow installation using either method. The innovative double-rod design allows you to separately hang a decorative shower curtain and a protective shower liner, or use the second rod to hang towels or clothes. The rod works with all standard shower curtains and liners, and adjusts without cutting to fit most standard shower or tub openings (from 44 to 72 inches).
