Friction Rock


Friction rock anchors are simply a long length of open seam, high strength steel tube. One end is equipped with a welded steel ring which retains a bearing plate. The opposite end is tapered to facilitate easy insertion into the drilled hole in the rock.

  • As a temporary, quick and easy support in development ends prior to the installation of more permanent support (should this be required)
  • Securing of wire mesh in underground excavations, road cuttings and open pit highwalls As an anchor to hang pipes and cables.
  • Determined by FRA diameter
  • These units are easy to install and all that is required is the appropriate driving tool and a percussion type drill (jackhammer, jackdrill, stopper etc). Drill a hole 1 to 4mm smaller in diameter than the FRA to be installed
  • Place the driving tool into the chuck of the drill
  • Place the bearing plate over the tapered end of the FRA
  • Place the tapered end of the FRA into the collar of the drill hole and align
  • Start the drill and drive the FRA home until the bearing plate is hard up against the rock face.
