The ännt SA275/M50-1200 is a high-security semi-automatic bollard designed for locations that require certified M50/K12 crash protection but do not need a fully automated system. Certified to ASTM M50/K12, this model is engineered to stop a 15,000-lb vehicle traveling at 50 mph, making it suitable for high-risk government, military, energy, and critical-infrastructure environments.
Operation is simple and reliable. The internal hydraulic mechanism is activated using a cordless screwdriver, allowing the bollard to rise or lower without heavy manual effort. This design provides strong physical security while avoiding the cost and complexity of automatic systems. The 1200 mm reinforced steel cylinder, heavy-duty base frame, and deep foundation structure work together to ensure extreme stopping power and long-term durability.
The SA275/M50-1200 performs consistently in demanding climates and integrates cleanly with surrounding security layouts. Its straightforward operation, low maintenance requirements, and certified impact resistance make it an excellent choice for facilities that require high protection with controlled, occasional access.
