When hammering-in the threaded rod, the plug expands in four directions as a result of the conical inner geometry.
The plug is set in pre-positioned installation. This can be done in two different ways: Pre-installation of the threaded rods in the plug with both being hammered into the wall together or pre-inserting of the RODFORCE into the drill hole followed by hammering-in of the threaded rod.
The teeth in the plug mechanically interlock securely with the metric thread of the threaded rod.
The unique elements on the outside of the plug brace against the wall of the drill hole.
