With a simple, clean design, the Twilight room darkening curtain rod beautifully complements and enhances any curtains or drapes. Its sleek form and matte finish can be easily integrated into a variety of different decors. Twilight curtain rod effectively blocks out all light. Its innovative wrap-around design helps prevent light leakage by allowing your curtain or drapery panel to rest directly against the wall. Wrap the panel around the curved end of the rod and tuck it behind the bracket to eliminate exterior light from seeping in. The drapery rod has a strong and stable 3/4 inch (2 cm) diameter, constructed to hold curtains from light to medium weights, with a maximum capacity of 22lbs. (10 kg). U.S. Patent No. D644,918
