- cable boxes can be made in three types: free-standing, wall-mounted and built-in,
- with regard to the built-in cable box, dimensions of the niche should be enlarged by 10 mm in relation to the box dimensions (similarly as in the picture of ZK-1 box),
- it is possible to manufacture boxes with different dimensions adjusted to the localization needs.

Mounting
Free-standing boxes are mounted on a prefabricated concrete foundation. This foundation allows cables to be conducted from four directions. View, dimensions and exemplary mounting instructions of the cable boxes are presented in the pictures below.
