Heavy-duty anchor for high loads in cracked and non-cracked concrete, ideal for flush-mounted fixtures, such as railings or handrails. Zinc-plated steel
  • High load-bearing capacities
  • Time-saving push-through installation
  • Immediate load-bearing capacity — no waiting
  • Torque-controlled expanding galvanised steel anchor
  • Countersunk head design for an elegant appearance (e.g. for railings)
Proof of Performance
  • ETA-02/0031 for individual attachment, option 1, cracked and non-cracked concrete, seismic performance category C1 and C2
  • Fire resistance: F30, F60, F90 and F120; exposure to fire according to DIN 1363-1:1999-10 (uniform temperature-time curve)
  • Fire resistance: R30, R60, R90 and R120; TR020 (included in ETA-02/0031)
