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