B¹ Electronics box and B¹ two-gang junction box

The B¹ electronics box and B¹ two-gang junction box are especially suitable for installations in on-site mixed concrete vertical formwork. The B¹ electronics box provides plenty of space for accessory installations, and additional space for devices such as switch actuators or other components for smart home applications. The relevant separator wall allows the standardised installation of bus and operating voltages in a single box. B¹ Two-gang junction boxes allow the installation of block and pre-wired accessories, and provide space for the assembly of cable for multimedia connections.
  • Plenty of space for accessories and cables
  • Separator wall for the standardised incorporation of two voltage types
  • Flat front part for fast, easy nailing
  • Innovative conduit entries for fast processing on the construction site
  • Slot for B¹ Prefix® system wing set
  • Spring travel ensures secure fit in standing formwork
