The TrafFix Water-Cable Barrier is designed with three (3) molded in galvanized steel cables that strengthen the water-cable barrier to resist vehicle penetration during an impact. The hinges are designed to allow a 30° pivot between sections and each hinge features a double wall knuckle design that greatly minimizes breakage. Each wall includes one (1) galvanized steel T-pin to securely link Water-Cable Barrier sections together.

The large 8" fill holes speed up the filling process reducing setup time in dangerous roadway work-zones. The tamper resistant drain plug has coarse buttress threads that eliminates cross threading and allows for quick insertion or removal with only 2½ turns. With large forklift/pallet jack slots, the water-cable barrier is easy to move when empty or full — further reducing time spent in workzones. The water-cable barriers can be stacked, while empty, for easy storage and transport to and from job sites.

Made from durable UV resistant polyethylene plastic, the TrafFix Water-Cable Barrier prevents breaking, cracking, and fading in most weather conditions.
