The Birkin 3/4" Fast Fit Easy Install Decorative Window Curtain Rod by Kenney is as easy to hang as a picture frame. Position the strong, innovative thermoplastic 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 rods provide excellent support, up to 25 pounds. * The telescoping steel rod adjusts from 42 inches to 120 inches to fit your window and projects 3.5 inches from the wall. A 3/4 inch diameter curtain rod is recommended for use with light to heavyweight curtains on larger windows and in larger rooms, like your bedroom, living room, and more.
