Barrier Arms

Anti-Ram Drop Arm Barrier

The barrier arm is a multi-purpose entry drop-arm that controls traffic while providing an anti-ram obstacle to protect from potential vehicular threats. We offer two different crash rated barrier arm options: the K12/L3 barrier arm and the M30/P1 barrier arm (also known as the M530).

The M530 has two successfully tested designs. The 22-foot barrier design does not require excavation across the roadway, whereas the 12-foot barrier design uses a shallow excavation across the roadway for a monolithic installation. The M530 barrier arm is also available in engineered design lengths to fit specific site requirements.
