- Excellent holding power due to spreading supporting elements with large contact radius
- Simple setting with associated mounting pliers
- Pre-assembled with metric pan head screw
- Anti-rotation lock on the collar prevents movement in the drill hole
- Pan head screw can be loosened without loss of holding power
Fire resistance tested in hollow pumice
The standard screw belonging to the anchor can be replaced by another fastening element with a metric thread of the same size after the anchor has been expanded. For example, screw hooks, speciality screws, A2/A4 brass screws, threaded rods, 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.
