2" Domed Bronze Concrete Survey Marker
Berntsen 2" Bronze Concrete Survey Marker The "CD" style bronze concrete marker has a ¾" (19mm) diameter x 2" (50mm) long stem and is notched to hold firmly in concrete or rock. It is available in 2" (50mm) diameter and one-piece orbital formed from solid unleaded silicon bronze bar. The CAPMAG ceramic magnet can be used with these concrete markers to assure easy detection of the mark with a magnetic locator up to 6 to 12 inches deep, depending on soil conditions. We have countersink drill bits made specifically to perfectly recess this CD2 concrete marker in existing concrete. CD2B Concrete Marker Installation Instructions
