B¹ one-gang box and B¹ one-gang junction boxes

B¹, the new on-site mixed concrete range of products for electrical installation work. In addition to the tried-and-tested system features such as the flat front part, sturdy fixing domes and the support element slot with a sprung box base, the new B¹ range has innovative conduit entries, sturdy slots for the new B¹ Prefix® system wing range, and also bridges – which can be broken out later if required – for connecting accessories in combinations.
  • Suitable for all types of formwork
  • Slot for B¹ Prefix® system wing set
  • Can be stably combined over the complete box body with a standardised combination distance of 71 mm
  • Innovative conduit entries for fast processing on the construction site
  • Signal bristles for easy location with installations on the opposing formwork side
  • Larger mounting and installation space
  • Installation of pre-wired installation accessories with multiple combinations, because the bridge can be broken out later
