Question about Dri-Box 200

The box is currently still under 1.5 metres of snow in the garden😀
In the last 3 winters with subsequent snowmelt, the box has held up really well.

It's like skender85 writes. There are of course no pre-punched screw holes.
However, you can of course screw it to the wall, e.g. through the base of the housing, and then seal it with silicone, for example. Or you can use 1-2 brackets to attach the box to the wall. A colleague of mine did this in the garden...

No, otherwise it is no longer tight.
