Not suitable for a black out blind

The brackets I bought a black out blind. Ansich makes everything a very stable impression. For the product deserved even 5 stars. But since it too far weghält the blind from the window frame and thus by the light shines on the sides and above, it is completely inappropriate for a black out blind. On cloudy days, it may still go, but on sunny days (even if the window is in the shade), it is so bright in the room that the whole point is completely missed. Pity!
