B¹ Prefix® system wings

The B¹ Prefix® system wing allows fast, easy fixing to the reinforcement. This means optimal installation on the opposing formwork side and for free-standing reinforcement, and also for sliding or travelling formwork constructions. All wall applications in the new B¹ range have slots for the locking of two Prefix® system wings. This ensures fast, easy installation on the opposing formwork side.
  • Fast and easy installation on opposing formwork without support element and abutment
  • Holding in place using the Prefix® installation technology leaves both hands free for securing with tie wires
  • A pronounced corrugated profile and additional fixing opportunities for secure fixing using tie wires
  • Combinable when using wall and ceiling transitions
  • For installation in exposed concrete, pressed against the front formwork
  • Suitable for 20 - 60 mm concrete covers
