- Excellent holding power due to spreading supporting elements with large contact radius
- Simple setting with associated mounting pliers
- Pre-assembled with threaded rod, washer and nut
- Anti-rotation lock on the collar prevents movement in the drill hole
- Threaded rod can be loosened without loss of holding power
Fire resistance tested in hollow pumice
After the anchor has expanded, the standard screw belonging to the anchor can be replaced by another fastener with a metric thread of the same size, e.g. eye bolt, screw with a special head, A2/A4 brass screw, threaded rod etc.
The lugs on the collar (anti-rotation lock) must be bent straight for hard surfaces, e.g. tiles. Pushing the front lever on the ratchet pliers releases the ratchet pliers again.
