The ännt RBS500K4 is a compact, surface-mounted road blocker certified to ASTM M30/K4. It provides reliable vehicle-stopping capability with zero excavation, making it ideal for quick installations and locations where ground disturbance is limited.

The ännt RBS500K4 is a shallow-profile, surface-mounted road blocker built for sites that need certified vehicle-threat protection without the ability to dig. Rated to ASTM M30/K4, the RBS500K4 is engineered to stop a 15,000-lb vehicle traveling at 30 mph, while using a fully above-ground design.

Its compact footprint makes it suitable for narrow passages, temporary setups, or locations where utilities, slabs, or construction restrictions prevent excavation. The reinforced blocking plate and stable surface frame deliver dependable impact resistance, and the hydraulic operating system provides consistent raising and lowering even under heavy use.

The RBS500K4 integrates cleanly with ännt access-control equipment and supports lights, loops, alarms, and standard safety features. Designed for tough environments and minimal maintenance, it gives planners a strong, flexible security option when digging simply isn’t an option.

Spec Sheet

Spec Sheet
  • 1. What makes ännt Bollards different from other perimeter protection manufacturers?

    Our certified products are backed by one of the most experienced teams in the industry — experts who ensure every solution is engineered, installed, and performing to the highest standard. We pride ourselves on having the best product and the best customer service in the industry.

  • 2. How do I know which bollard or barrier is right for my project?

    Our team provides tailored guidance for every application. We review your site conditions, access needs, and threat requirements to ensure the correct model, foundation type, and configuration are specified from the start.

  • 3. Are all ännt products certified or crash-rated? What’s the difference?

    Many of our systems are crash-rated to PAS 68, ASTM M-series, and IWA 14-1 standards. Non-rated models share the same engineering precision but are designed for light-duty or architectural applications where certification isn’t required.

  • 4. Can ännt Bollards work directly with my architect, contractor, or security consultant?

    Yes. Collaboration is at the heart of what we do. We frequently partner with design teams, contractors, and consultants to simplify coordination, maintain compliance, and ensure efficient installation.

  • 5. Do your systems meet international standards for crash testing and safety?

    Yes. ännt’s crash-rated products are independently tested and certified to meet recognized global standards, including PAS 68, ASTM M-series, and IWA 14-1 — ensuring proven performance and consistent results on projects worldwide.

  • 6. How do your bollards perform in harsh winter conditions?

    Our bollards are engineered to perform reliably in extreme climates. Heated components, sealed enclosures, and drainage systems prevent freezing, while corrosion-resistant materials ensure long-term durability through snow, salt, and ice.

  • 7. Can ännt customize bollard finishes, materials, or operation types for specific site requirements?

    Yes. We offer multiple finishes, materials, and operation types — including automatic, semi-automatic, and removable models — with options for lighting, access control, and aesthetic integration to suit any environment.

  • 8. How quickly can products be delivered or installed once a project is approved?

    Lead times vary by model and project size, but we maintain efficient production and logistics channels to support fast turnaround across North America, with installation guidance and support available where needed.
