With the Ultra Slim RJ45-RJ45 connector with a speed of 10/100 Mbps, you can easily connect your network through the window frame. Open the window, place the RJ45 window grommet between them, close the window, done. There is no need to drill into the wall.
The window step is fine enough (approx. 0.3 mm) to close the window properly and at the same time strong enough to support many window openings. For a better hold, the grommets can be additionally fixed using the supplied screws and two 3M adhesive strips.
