The MVB II Modular Vehicle Barrier is a tested and certified light weight, portable barrier that has been designed to prevent hostile and non-hostile vehicles from entering controlled areas. The barrier is extremely cost effective, simple to assemble and easy to compact. It can be used on rocky, rough or sandy terrain, gravel and asphalt. The product successfully prevents vehicle attack by transferring the momentum of the vehicle to the ground. The barrier improves safety and supports security forces. To increase the effectiveness of the barrier, ground anchors can be added along with a Pivot System Accessory which will transform the barrier to a swing gate.
