The ROCK ROAD SAFETY WB500 is a 72" × 36" polyethylene water-filled barrier designed to provide temporary traffic control and site protection. When filled with water, this interlocking barrier creates a stable, highly visible perimeter for work zones, construction sites, parking lot delineation, and crowd control applications.
Constructed from rotationally molded high-density polyethylene, this barrier resists UV degradation and impact damage from jobsite conditions. The white finish provides high daytime visibility, while the low-profile design minimizes wind resistance. Each unit features an integrated connecting pin system that allows multiple barriers to interlock, forming continuous runs without gaps. Forklift pockets on both ends simplify transportation and placement with standard material handling equipment.
Key Features
72" × 36" Footprint — Provides substantial traffic separation while maintaining a manageable size for repositioning
Water-Fillable Design — Lightweight when empty (78 lbs) for easy transport; stable and impact-resistant when filled
Interlocking Pin System — Connects securely to adjacent barriers to create continuous barrier runs without separation
UV-Resistant Polyethylene — Withstands prolonged sun exposure without cracking or fading
Forklift-Compatible — Built-in pockets allow quick placement and removal with standard forklifts or pallet jacks
High-Visibility White — Stands out clearly in daylight conditions for enhanced driver awareness
Applications
Widely used by DOT contractors, utility crews, municipal public works departments, and event management companies for highway work zone protection, lane closures, construction site perimeters, parking lot reconfiguration, and pedestrian crowd control. Suitable for both short-term and extended deployment in temporary traffic control plans.
