Berntsen G Series Drive-in Piston Monuments - lightweight & quick to install

The all-aluminum "G" Series monuments are sturdy, lightweight, and much easier to install than concrete bound monuments - in most soils you just drive them in!  This makes them perfect for surveys where speed of installation is a main concern.  All of the drive-in monuments have magnets installed to aid location with a magnetic locator, and all can be customized to your specifications.

The optional G2 Tap-on Cap offers a 3-1/4" (83mm) stamping surface (the same as on the monuments with larger pipe diameters). It is orbitally formed from solid series 6000 aluminum bar. The optional cap is tapped onto the pipe after the monument is driven into the ground. Specially designed serrations and a unique rim design help lock the Tap-On Cap to the G1 Drive-in Piston Monument or G1BR Aluminum Drive-in Breakaway Monument driving cap.
