Transform your window decor with a Zenna Home Twist and Shout Window Curtain Rod, featuring newly improved tension mounting that's made for effortless installation with no drilling and no tools. This adjustable curtain rod extends from 28 to 48 inches, and works with any standard window curtains or panels. (For larger spaces, longer Twist and Shout rods are available that adjust from 48 to 84 inches.) The rod installs quickly and securely on the inside of your window frame. Its patented Twist and Shout technology has been updated to ensure the rod holds firmly in place on a wide array of window frame materials and styles, now including uneven decorative surfaces. On flat metal and plastic frames (including aluminum and other metals, as well as fiberglass or vinyl), simply install using the included rubber pads. On decorative drywall or wood frames, the new Twist and Shout pin pad securely holds the rod in place. The pad's pins grip the inside surface of your window frame. (Note that the pin pad will leave very small holes on the inside of the frame.) With either installation choice, the tension curtain rod supports up to 20 lbs. Easy-to-follow illustrated installation instructions are included. Installation Tip: Ensure you have at least 5 inches of clearance on either side of your window frame for best results.
