The Sentry Water Cable Barrier

The Sentry Water Cable Barrier is an NCHRP 350 TL-3 certified work zone crash barrier.

The Sentry is intended as an alternative to cumbersome concrete barriers in a construction work zone. The Sentry has been tested and passed all TL-2 and TL-3 light and heavy vehicle impacts at 45 and 62.5 mph (70 and 100 kph). With eleven (11) interlocking knuckles on each end multiple Sentry's can be linked together with a 1 ⅛" (30 mm) diameter galvanized hollow steel T-Pin with a steel keeper pin at the bottom of each T-Pin.

Molded into each Sentry are four (4) ⅜" (9.5 mm) diameter stranded steel cables, that are galvanized for excellent corrosion resistance. The cables prevent the impacting vehicle from penetrating the barrier wall and into the work zone or on-coming traffic.
