GRAB – 300 (ASTM M50)

The Ground Retractable Automobile Barrier (GRAB-300) system is an active vehicle barrier that has met the demanding ASTM M50 test criteria established by the Department of Defense. The system provides ultimate security while reducing the likelihood of injury to vehicle occupants. In numerous real world impacts, GRAB systems have effectively stopped vehicles weighing up to 80,000 pounds and vehicles traveling at speeds reaching 50 mph. The GRAB system has been the barrier of choice for government agencies, military, petrochemical industry, and a wide variety of corporate companies and civil clients.
