The box is sealed with EasyFoam stoppers. These are delivered with the box in the correspondent size. When the cables are laid, layers are cut into the stoppers for the cables to run through. A normal cutter can be used for this. Then the stopper are put into the box opening.

It is recommendable to cut the stoppers a little larger so that they are slightly compacted in the box opening.

All the other layers left in the edges or between the cables for example, are filled with EasyFoam mounting foam or with a conventional sealing compound just like silicone. Our foam is recommened especially when there are many openings left and it would take too much time to seal them with silicone.
