  • When setting the anchor, the anchor sleeve is driven over the cone with a hammer (or setting tool) and fills the undercut hole with a positive fit.
  • Also available: special version FZA ST A4 for man hole step irons according to DIN V 1211 GS / 1212 GS.
  • A4 stainless steel version for outdoor use and in damp conditions, highly corrosion-resistant steel C (material no. 1.4529) for applications in aggressive atmospheres.

  • Positive fit in the undercut gives additional safety.
  • Virtually expansion-free operation allows cost-efficient fixing with very small edge distances and axial spacings.
  • Single-step drilling process simultaneously produces the undercut, saving installation time.
  • Green ring becomes visable when correctly set.
