The ännt RB1000K12 is a high-security shallow-mount road blocker designed for critical infrastructure, government facilities, logistics sites, and any location requiring maximum vehicle-threat mitigation with minimal excavation. Certified to ASTM M50/K12, the RB1000K12 is engineered to stop a 15,000-lb vehicle traveling at 50 mph while using a fitting depth of only 300 mm.
This shallow-foundation profile makes the RB1000K12 a strong solution for areas with buried utilities, reinforced concrete slabs, restrictive ground conditions, or sites where deep foundation work is limited or not allowed. The system features a reinforced steel blocking plate, a durable support frame, and a reliable hydraulic operating unit built for heavy, repeated use.
The RB1000K12 integrates cleanly with standard access-control and safety systems, including lights, loops, and alarms. It is built to perform in demanding climates and is engineered for long-term reliability with straightforward maintenance requirements.
Overall, the ännt RB1000K12 delivers top-tier crash performance, shallow installation, and dependable operation, giving planners and engineers a practical way to bring maximum protection to complex sites.
