Before installation, use a steel tape measure to mark the drilling positions on the top of the window frame. Generally, it should be 2 inches. Ensure that the two holes are on the same horizontal line and there should be no deviation in front or back. Otherwise, after the shades is installed, it will be tilted, which will also affect the disassembly and use of the shades.

Note: When installing the Roman Shades, pay attention to the white plastic pieces at the top of the track (the highlighted part in the picture). The brackets should not be fixed in these positions.
