Practical and quick solution against annoying insects

We have the insect screen frame get even faster than indicated. It's practical, nothing has to be assembled or sawn. Unpacking and inserting directly.
This is made very easy.
Stop at the level of the roller shutter guide and far apart to push the Schiebefix in the guides of the roller shutter is stuck right and left, then lowering the roller shutter up to the frame. Done.

Since we do not use the Schiebefix in the bedroom there is no problem with the lack of blackout.

A suggestion to the manufacture would offer this Ramen with higher dimensions, because the role, depending on the window height is closed but quite far.

However, when only a quick fix for evening / nighttime aeration needs is the Schiebefix an inexpensive, quick and easy solution.
