The ännt FB275/K12-900 is a permanently installed, crash-rated bollard engineered for high-risk environments where maximum stopping power is required. Certified to ASTM M50/K12, this model is designed to stop a 15,000-lb vehicle traveling at 50 mph, providing one of the highest levels of impact resistance available in a fixed installation.
The 900 mm reinforced steel cylinder anchors into a deep-foundation steel frame, creating a rigid, non-yielding barrier that cannot be lowered or removed. This makes the FB275/K12-900 ideal for military compounds, government facilities, data centers, critical-infrastructure sites, logistics terminals, and any area requiring permanent high-security perimeter protection.
With no moving parts, the fixed design offers long-term durability and minimal maintenance. Built from high-grade steel with optional stainless-steel finishes, it integrates cleanly with ANNT’s automatic, semi-automatic, and removable models to create consistent sitewide protection.
The FB275/K12-900 delivers top-tier crash performance, a permanent security footprint, and reliable performance in demanding outdoor environments.
