Over the window, the space is selected by dark track, not by Roman pole.
The walls above most windows are very narrow in order to enlarge the windows. When the wall height above the window is less than 15 centimeters, it is not recommended to choose the Rome pole track. First, the installation position is not enough, and second, the upper edge of the curtain is easy to expose. Underground track can effectively solve these problems.
No room to open the window, no curtain
Many households open windows in the upper position, and there is not enough room for the front and back of the window, if the curtain is easy to open the window, this time the choice of delicate curtain is more practical than the curtain.
