Resin Anchor Rod VMZ-A A4


Anchor Rod for push-through and put-before mounting in concrete tensile zones in M&E services and plant construction (for anchoring heavy loads).
Suitable for attaching brackets, pipelines and channels.

  • No special drill required
  • Heavy loads
  • Small edge and centre distance
  • Approved for use under seismic action according to the performance category C1 and C2 (M10 - M16)

Scope of delivery

Pre-assembled with washer and hexagon nut.


Drill hole according to min. setting depth vertically to the surface.
Careful cleaning of drill hole with Steel brush and Blow-Out Pump.
Screw Mixing Nozzle onto the cartridge; foreshots to be removed and fill 2/3 of drill hole with resin starting from botton of the hole.
Drive the anchor manually into plastered borehole up to its embedment mark.
When reaching the embedment mark, plaster must be apparent.
Respect hardening time, when tighten the anchor with instructed torque.

Detailed assembly instruction is attached to the product.
