The Fast Fit Birkin 5/8" Easy Install Decorative Window Double Curtain Rod by Kenney is as easy to hang as a picture frame. Position the innovative brackets onto the wall and tap the included nails into place. Using nails instead of screws leaves less damage behind on the wall. The easy installation doesn't sacrifice performance, as the Fast Fit curtain rod provides excellent support, up to 25 pounds. The telescoping steel rod adjusts from 36 to 66 inches or 66 to 120 inches to fit your window. The front rod projects 3.86” while the back rod projects 1.86” from the wall. A 5/8 inch diameter double curtain rod is recommended for use with light to medium weight curtains in your bedroom or living room and adds a layered look to your window. Layering curtains gives you more control over how much light to let into your room throughout the day and provides more insulation during colder months. To layer, place heavier, decorative curtains on the 5/8" diameter front rod and lighter, sheer curtains on the back 5/8" diameter rod. Drapery Hardware Set Includes: one telescoping steel double curtain rod with decorative finials (2.86" H x 2.06" W x 2.06" H), two brackets, one center support, nails, measuring template, and installation instructions.
