The Sun Zero Bronn Industrial 3/4" Room Darkening Double Curtain Rod is designed to wrap around your window frame to save energy, block light, and reduce noise. The textured matte black finished industrial styled telescoping pipework steel rod is adjustable from 66-120" to fit a variety of window sizes and projects 3.75" from the wall. Use on larger windows in larger rooms, like your bedroom, dining room, or living room to hang light, medium, or heavyweight curtains. The textured finish make this curtain rod ideal for hanging curtains with grommets or with clip rings. The double rod adds a layered look to your curtains, giving you more control over how much light to let into your room throughout the day and providing more insulation during colder months. To layer, place heavier, decorative curtains on the 3/4" diameter front rod and lighter, sheer curtains on the 5/8" diameter back rod. Pair with Sun Zero curtain panels (sold separately) to maximize energy saving, light blocking, and noise reducing features.
