2.	The barrier width shall cover a true clear opening from 96 inches (2.43 M) to 192 inches (4.88 m). The barrier width shall range from 106.5 inches (2.70 M) to 202.5 inches (5.14 M).

3.	The foundation depth of the barrier frame shall not exceed 19 inches (482.6 mm).

4.	The barrier vault assembly shall consist of an engineered watertight base, with a natural gravity drain, to remove water from the foundation. A drain and sump pump connection opening shall be supplied in the bulkhead of the watertight base.

5.	When the barrier is in the retracted position, there is no weight limit for vehicles.

6.	Barrier shall not use springs, cable tensioners or any other mechanical means to obtain an Emergency Fast Operation (EFO) state. Emergency Fast Operation shall be obtained only through the use of the supplied actuator and drive system.
