The ännt SA275/K4-900 is a semi-automatic, crash-rated bollard engineered for sites that need dependable vehicle-impact protection without the cost and complexity of a fully automatic system. Certified to ASTM M30/K4, the SA275/K4-900 is designed to stop a 15,000-lb vehicle traveling at 30 mph, making it a strong choice for commercial sites, municipal facilities, logistics yards, research campuses, and controlled-access roadways.

The bollard uses an internal hydraulic mechanism that is activated with a cordless screwdriver, allowing it to rise and lower smoothly with minimal manual effort. The reinforced 900 mm steel cylinder and heavy-duty foundation structure provide reliable crash performance, long-term durability, and consistent operation in tough climates.

It integrates easily into ännt perimeter-protection layouts and works well in environments where access is occasional but certified crash protection is still required. With proven rating performance, simple operation, and low maintenance needs, the SA275/K4-900 is an effective solution for secure access control without automation.

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.
