Floor junction box BAK4 to slab formwork

Floor junction box BAK4 to slab formwork

Plenum box BAK4 for fastening to the slab formwork.

The installation of underfloor ducts requires a minimum height of the concrete cover (60mm). If this height is not available, special boxes can be obtained for concreting into the raw slab. After fastening to the formwork, they are connected to each other with underfloor trunking 200 x 40, covered with the temporary protective cover and poured into the concrete up to the top edge.

The installation kit is mounted on the levelable box insert; the opening between the box bottom and the installation plate allows the cable to pass through to the next box. After finished wiring, an aluminum cover with cable trough is attached.
