126.96.36.199 Testing. The manufacturer tested this barrier with a 10,000-pound (4,545-kg) vehicle,
traveling at 15 mph (24 kph), that failed to penetrate the barrier. This equates to kinetic energy
absorption of 34,400 ft-lbf (4,700 kgf-m).

mechanism. The design will accommodate openings from 10 feet (3 m) to 60 feet (18.3 m).
184.108.40.206 Testing. This barrier has not been crash-tested; however, calculations provided by the
manufacturer show it is designed to stop a 5,000-pound (2,272-kg) vehicle traveling at 30 mph
(48 kph) with a penetration of less than 6 feet (1.8 m). Contact the manufacturer for cost data.
