HySecurity StrongArm M30 and M50 anti-ram vehicle barrier arms reliably defend high-security sites worldwide. Unique dual arm design prevents a large truck or a small passenger vehicle from breaching the security perimeter. Stop a 15,000 lb truck driving 30 mph/50 mph in its tracks. Bright LED arm lighting and highly reflective tape on the upper arm, plus a standard traffic light, boost visibility and inhibit accidental impact. The lower arm, at bumper height, reduces possible injury or death from an accidental passenger car gate strike. HySecurity backs an unequaled 5-year reliability/quality assurance warranty. CE Certified.
