The Ground Retractable Automobile Barrier (GRAB-300) system is an active vehicle barrier that has met test criteria of ASTM 2656-07 M50/P2 (15,000 lb truck at 50 mph, Penetration 3.31' to 23.0'). The system provides ultimate security while providing a less-than-lethal solution utilizing a patented energy absorbing system upon impact. In numerous real-world impacts, GRAB systems have effectively stopped vehicles weighing up to 80,000 lbs and vehicles traveling at speeds over 50 mph.
