Curb Boxes

Curb boxes are protective access enclosures used to house and provide surface access to buried curb stops and service line valves in municipal water distribution systems. They allow operators to locate and operate underground shutoff points without excavation while protecting the valve assembly from soil, debris, and surface loads. Commonly used in residential, commercial, and municipal water service applications, curb boxes are typically installed at property lines where water service enters a building. Available in adjustable and fixed-height configurations and constructed from cast iron, ductile iron, polymer, or composite materials, curb boxes are designed for long-term durability and reliable access in underground utility systems.
