Very easy to install with the small double sides to keep in place during screwing. Very good quality, spring maybe a little too tight it clicks to the stop if you let go of the blind.
Blinds that replace old curtains. It is really ideal for the modernization of an old boat. Mosquito net and blackout curtain in the same very thin box are the strengths of this very aesthetic product. The fault is only in the plastic covers of the screws, which must be handled with great care. Be careful with vaulted ceilings, you must provide for the application of mastic, because the blind is only fixed by 4 screws. I recommend this product!
