NMSB XI (Figure 19) is a surface-mounted barrier with a gate arm that is also available
from Nasatka. It has been crash-tested by the manufacturer. This system is frequently used for low
impact conditions (when vehicle speed can be limited) and as the inside barrier (after a primary high
impact barrier) for vehicle inspection areas or sally ports. Performance and cost data are shown in
Table 9.
