Group Arrangement of WD90 Cable Boxes |
 |
 |
 |
|
 Possible group arrangements depend on the box size and the wall type.
In general, there must be a 1.5 cm seam of mortar or plaster filling up the entire space between two cable boxes. It must fill up the entire space between the boxes inside the wall or ceiling. When a group is installed in a light partition wall it is also necessary to install a bolt above and below each box. If more than two boxes are installed in ceilings in front of one another, they must be screwed together with distance anchors.
