Gibraltar's G-6532 Modular Vehicle Barrier (MVB) is tested and certified to ASTM F2656 M30 P2 requirements. The patented portable unit is one of the lightest portable barriers available to carry an M30/P2 certification. The unit is modular in design and can be connected to other MVB units to create 360 degree portable protection from vehicles. If you require anti-pedestrian fencing, we fabricate panels that can be attached to the units as well, to keep personnel out of the protected area.
