Extra Passover rings maybe required for the Sunflex Belgravia Bay Window Curtain Pole when hanging wide curtains with lots of stacking or to simply offer the curtains extra support. When used in conjunction with the Belgravia Passover Brackets, the Passover rings allow the curtain to glide round the corner without obstruction. The rings are supplied in packs of 4 and available in satin steel, brass, black nickel and antique brass to match the poles perfectly.
