ATCRB-12 Crash Rated Beam (U.S. DOS K12)

DOWNLOADS

The ATCRB-12 crash rated beam features an articulating drop arm, the ability to clear openings up to 40′, and is ASTM F2656-07 M50 P2 certified (equivalent to Department of State K12). The unusually large clear opening provided by this K12 crash beam boasts a breakthrough in vehicle crash testing. This combined with its ability to operate continuously or remain either deployed or retracted indefinitely regardless of local weather conditions presents perimeter security designers with an exciting new option for preventing vehicle intrusions. Finally, multiple drive lanes can be safely closed down with complete 15,000lb 50mph vehicle barrier protections without requiring huge adjacent recess area to store the barrier while not in operation.
