The ännt SA275/K12-900 is a semi-automatic bollard engineered for high-security applications where certified vehicle-impact protection is required, but a fully automated system is not necessary. Tested to ASTM M50/K12 standards, the SA275/K12-900 is built to stop a 15,000-lb vehicle traveling at 50 mph, making it suitable for government compounds, military installations, critical infrastructure, and sensitive commercial environments.

This model uses an internal hydraulic system that is operated with a cordless screwdriver, allowing the bollard to rise or lower smoothly with minimal manual effort. The design provides strong physical security while keeping installation and maintenance simpler than automated systems. The reinforced 900 mm cylinder and deep foundation structure ensure reliable stopping power, long-term durability, and stable performance in harsh climates.

The SA275/K12-900 integrates cleanly within broader ännt perimeter-protection layouts and works well in locations where access is occasional but high-impact protection is essential. With certified crash resistance and straightforward operation, it offers an effective balance between maximum security and practical usability.

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.
