Shallow mount wedge barriers are among the most versatile physical security products on the market because of their compact footprint and robust design. They provide maximum security for high-threat locations—especially those with potential high-speed impact conditions, limited response times and minimal property setbacks. The XT-2000 Shallow Mount Wedge Barrier boasts a 41-inch deployment height for added protection against vehicles with a higher chassis and offers pleasing aesthetics, quiet operation and efficient installation.

Design Features

The XT-2000 Viper Shallow Mount Wedge Barrier is comprised of a high-quality, structural steel frame and plate that, when raised, creates a wedge-shaped barricade to seal off roadways and prevent vehicle access. The wedge design is very popular because it effectively transfers high impact loads into a relatively compact foundation. Yet remarkably, the XT-2000 only requires 16-inch (400 mm) deep excavation and 3 cubic yards of concrete, which shortens installation time and reduces cost. A hydraulic power unit (HPU) housed in an above-ground NEMA-rated control enclosure activates the barricade, lifting the plate in 5 seconds for normal operation and 1.5 seconds in Emergency Fast Operation (EFO) mode.

The Viper is available with many equipment options for managing operation including control consoles, traffic equipment, safety loops and environmental controls. Because all of the equipment is near ground level, this barrier is easy to maintain. The Viper is ideal for the following conditions:

  • High-speed impacts – where the roadway layout allows vehicles to reach higher speeds
  • Minimal setbacks – where critical assets or equipment are located close to entrances (such as in urban areas) and a high level of security is required regardless of potential vehicle speed
  • Fast deployment  where the barrier needs to be deployed quickly because it is located close to the guard booth and reaction time is therefore minimal
  • High traffic – used as a final denial, this barrier can be used in tandem with standard traffic arms to process a high number of vehicles faster than other barrier types
  • Site restrictions – where flush mounting with the roadway surface is required for snow plowing or where buttresses and posts used in other barrier designs would prevent access for wide vehicles
  • Bicycle/motorcycle access – where preventing access by two-wheeled vehicles is desired
  • Excavation limits – where underground utilities, high water tables or other site conditions limit excavation depth
  • Space restrictions – where there is not enough room for beam-style barrier buttresses and foundations
  • Debris buildup – where debris accumulation can cause operational issues
  • Sound restrictions – where noise levels are a concern


The XT-2000 Shallow Mount Wedge Barrier provides ASTM F2656-07 M50-P1 crash tested security for high-threat and demanding environments while minimizing visual and audible impact to the surrounding area. It also has minimal foundation requirements, Emergency Fast Operation (EFO) and continuous-duty rating, making this barrier ideal for broad range of high-security facilities such as embassies, military bases, nuclear power plants, refineries and airports.

Technical Data

The XT-2000 Heald Viper incorporates many unique features that increase security, simplify installation and enhance the end user experience. With a deployment height of 41 inches (1049 mm), it reduces the risk of penetration by vehicles with higher chassis. A unique steel skirt shields the internal moving components, lends aesthetic appeal, protects pedestrians from injury and minimizes the accumulation of debris. Linkage bars ensure quiet operation, which is important in locations where noise is a concern. Additionally, rebar is integrated into the Viper’s frame and provided by Ross, eliminating the need for installers to furnish and build a separate rebar cage.

As an ISO 9001:2015 certified company, Ross is committed to making products of the highest quality. And as part of our pledge to quality assurance, we put every piece of equipment under extensive Factory Acceptance Testing prior to shipping. This testing process involves assembling, running and labeling all components including wiring harnesses, hydraulics and controls. This helps ensure simple and efficient installation in the field. We encourage all of our customers to attend this testing for training and final systems verification.
