The NMSB VIII is a single-buttress, bolt-down mounted barrier for high-threat security facilities. The NMSB VIII is engineer rated to stop a 15,000-pound vehicle traveling at 30 mph which is equivalent to DOS K4 L3 or ASTM M30 P1. The average barrier opening is 10′ (3.05 meters). Each barrier is hot-dip galvanized for years of service and includes a NEMA standard, self-contained attached housing unit. Standard barrier deployment time is three to five seconds and emergency up (E-UP) is from one to two seconds. Manual operation is provided without the need for hydraulics or power. Integrated traffic lights and gate arms can be ordered with the barrier, providing a comprehensive safety and security system. Clear opening sizes from 8 ft. to 15 ft. are available. In the fully “secure” (up) position, the barrier strike-plate height is 33 in. above ground level. Typical power for this barrier is 208v, 1 or 3 phase, 50hz or 60hz.


Two power options are available:

  • Integrated electric power unit (EPU)
  • Remote electro-hydraulic power unit (HPU)


No weight restrictions are placed on vehicles traveling over this barrier
