Sentry™ Water Cable Barrier

The Sentry™ Water Cable Barrier is an NCHRP 350 TL-3 certified work zone crash barrier that can be used as an alternative to concrete barriers in a construction work zone.

It has been designed with eleven (11) interlocking knuckles on each end so that multiple Sentry's™ can be linked together. The barriers are linked with a 30 mm diameter galvanized hollow steel T-Pin with a steel keeper pin at the bottom of each T-Pin.

Also molded into each Sentry™ are four 9.5mm 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.

How it works:
The Sentry™ Water-Cable Barrier softly absorbs the impacting vehicles energy progressively using water and the steel cables to capture the vehicle without redirection, avoiding a secondary incident.

The end result is that the errant vehicle is prevented from entering the work zone, captured and not directed into traffic, safely controlled and stopped which increases the survival rate of occupants and workers.

Testing Compliance:
The Sentry™ has been tested and has passed all TL-2 and TL-3 light weight (820kg) and heavy (2,000kg) vehicle impacts at 70 and 100 kph
