The Double Dusk Curtain Rod features an innovative wrap-around design which 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. Double Dusk is a strong and stable 5/8 inch diameter rod, constructed to hold curtains from light to medium weights, with a maximum capacity of 22 pounds.
