Long-Life Survey Marker
Berntsen drive-in pipe monuments provide solutions for many different situations. All styles include metallurgically matched combinations for longer life. They are lightweight and easy to transport, and are easy to relocate magnetically. Custom lengths are available, as are custom logos and designs. The optional G2 Tap-on Cap offers a 3 1/4-inch (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.
