The ännt RBS1000K4 is a high-security surface-mounted road blocker designed for locations that require strong vehicle-mitigation performance but cannot accommodate traditional foundation work. Certified to ASTM M30/K4, the RBS1000K4 is engineered to stop a 15,000-lb vehicle traveling at 30 mph while sitting entirely above grade.
Because it does not require excavation, the RBS1000K4 is well suited for sites with underground utilities, hard surfaces, restricted construction zones, or areas needing rapid deployment. The system features a reinforced blocking element, a stable surface frame, and a dependable hydraulic operating unit designed for frequent use.
The RBS1000K4 integrates easily with common access-control systems, enabling connection to lights, loops, alarms, and standard safety devices. Its rugged design performs consistently in demanding environments, offering a practical balance of mobility, strength, and reliability.
Overall, the ännt RBS1000K4 delivers certified crash performance in a fully surface-mounted package, giving planners a flexible and effective way to secure vulnerable access points without excavation.
