The most elegant solution for roof windows to keep out the pests. The assembly was a bit tricky, because in the instructions are only imaging without text and not all details could be seen exactly. But the result is more than satisfactory. Precise operation is a prerequisite for a good result. The construction can be shortened, which I have not done and which greatly facilitates the whole length and width. The color of the aluminum profiles is slightly darker than the pictures. A good product at a good PL ratio.
