B¹ ceiling junction box

The new B¹ ceiling boxes simplify installation on the ceiling formwork. The innovative conduit entries enable conduits to be easily inserted into several ceiling boxes arranged in a row without having to cut them during the laying work. Due to the conduit entries located higher up, additional cut-outs of the reinforcement bars are unnecessary, ensuring fast insertion of the empty conduits on the ceiling.
  • Suitable for all types of formwork
  • Flat front part enables smooth insertion of the reinforcing bars on the ceiling formwork
  • Innovative conduit entries for fast processing on the construction site
  • Larger mounting and installation space
  • Mounting of a light hook in accordance with DIN EN 60670
  • The proven KAISER colour coding system ensures that the installation can be checked quickly

Installation on the ceiling formwork

The exact position of the ceiling boxes is determined by means of a cord or tensioning a mason's lacing cord.
