Frankly I'd try anything to keep my blinds blackout boats on my Alu Wood windows without drilling. After several back and forth in DIY stores or I could not find my happiness, I finally decide to buy these hooks. Results: no drilling, does not prevent the correct window and close the curtains hold very well! In short if I had I would have to buy before! For me the only flaw: first only the white color is (a qd transparent or imitation wood?), Supplied in a box loose with adhesive (which are useless ??? No instructions included) . But really I quibble as these hooks c is awesome!
