The NMSB XII is DOS K12 L3 certified to stop a 15,000-pound vehicle traveling at 50 mph. The average barrier opening is 10 ft. (3.05 meters). In the up position, the top of the barrier is 32 in. above the ground.

The operator enclosure and beam receiver are hot-dip galvanized for years of service. Standard barrier deployment time is 4 – 10 seconds depending on crash beam length and operator configuration settings. The crash beam can be operated manually using its built-in counterweight system allowing for operation during power failures or hydraulic failures.

Two power options are available:

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