Berntsen CD2L Leveling Concrete Marker - works with level rods & standard prism poles
Perfect for situations requiring horizontal and vertical location, the CD2L features a raised datum point wth a small center dimple that works well with flat bottomed leveling rods or standard prism poles. Intended for use in concrete the CD2L is 2" in diameter and can be customized with a double row of lettering around the perimeter.
Our aluminum material is versatile and resistant to most environment conditions, however, if the survey markers are intended to be used in high traffic or caustic environments, such as roadways or salty conditions, we highly recommend using bronze survey markers to improve the lifetime of the markers.
The CAPMAG ceramic magnet can be used with these concrete markers to assure easy detection of the mark with a magnetic locator 6 to 12 inches deep, depending on soil conditions.
The CD2DRL countersink drill bit is made specifically to perfectly recess this CD2L concrete marker in existing concrete.
