Product Details


Berntsen 4" Bronze Concrete Utility Marker

Berntsen Concrete Utility Warning Markers are a perfect defense against damage to buried facilities.

The "C" style bronze concrete marker has a 23/32" (18mm) diameter x 2 3/4" (50.8mm) long stem and is flared to hold firmly in concrete or rock. It is available in 4" (50mm) diameter and one-piece orbital formed from solid unleaded silicon bronze bar. These markers can be placed in either wet concrete or drilled and epoxied into existing concrete.

The CAPMAG ceramic magnet can be used with these concrete markers to assure easy detection of the mark with a magnetic locator up to four feet deep.

The C4DRL countersink drill bit is made specifically to perfectly recess this C4FB concrete marker in existing concrete.
