Sentry TL-3 Water-Cable Barrier

Sentry TL-3 Water-Cable Barrier

The Sentry Water-Cable Barrier is a practical alternative to traditional concrete barriers specifically designed for construction work zones. This barrier has successfully undergone testing and exceeded the criteria for TL-3 impacts at speeds up to 62.5 mph (100 kph), ensuring reliable protection in critical areas.

Integrated Strength: Each Sentry module is reinforced with four ⅜” (9.5 mm) diameter galvanized stranded steel cables, providing robust resistance against vehicle impacts. Units can be seamlessly connected via interlocking knuckles and a 1⅛” (30 mm) diameter galvanized steel T-Pin, creating a continuous barrier that safeguards against vehicle intrusions into oncoming traffic or work zones.

Transport and Storage Made Simple: The Sentry’s design includes in-molded stacking lugs to facilitate convenient transport and storage, highlighting its user-friendly nature.

Lightweight and Adaptable: Weighing less than concrete alternatives and free from the need for anchoring, the Sentry is particularly suitable for bridge deck applications, reflecting its adaptability and ease of deployment.
