Twilight 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. Twilight has a strong and stable 3/4 inch diameter, constructed to hold curtains from light to medium weights, with a maximum capacity of 22lbs. This double curtain rod can support 2 curtains and is available in multiple sizes. *Note: 3/4″ (1.9 cm) diameter rod includes a 5/8″ (1.6 cm) diameter back rod. Includes one centre support bracket.
