M530 & M550 Barrier Arms

M30 & K12 | 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 M550 is K12/L3 rated and M530 is rated as M30/P1.

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.
