The SENTINEL Barrier was previously manufactured by ATG Access, Inc. and is now owned by Ameristar. It is the exact same product listed on the DoD as Sentinel Barrier under ATG. Ameristar's Sentinel wedge barriers are designed for maximum perimeter entry security. The potential for an unauthorized vehicle to enter a secured location presents a real and everyday threat that must be addressed. Combat vehicular threats at your perimeter's entry point with the Sentinel wedge vehicle barrier. The Sentinel anti-ram vehicle barrier also features a full security guard height of 38" and is available in various widths. Plus, its shallow in-ground installation requires an excavation of only 19", allowing 12" for barrier height and 7" for the foundation pad. When installed, the unit is completely flush with the roadway surface, requiring no side pillars or above grade assemblies. In addition, the hydraulic operating cylinder is concealed behind a tamper-resistant panel.
