Berntsen Break-Off Pipe Monuments - location is preserved even if survey monument is disturbed

Berntsen offers three models of break-off pipe monuments. All are designed to break at a predetermined point in case of disturbance or vandalism, even if the entire pipe and survey cap are removed. They all feature a high-strength permanent ceramic magnet in the break off base for easy re-location.
