Dura - Valve Box - 15X21X6 Extension Box W/O Lid Black

The large rectangular extension body adds approximately 6 inches of additional depth to an existing large valve box installation, providing clearance for tall actuators, flow sensors, or additional plumbing without excavating the main body.
Overview Designed to stack between the main body and the existing lid, this extension adds approximately 6� of interior chamber depth to any standard large rectangular valve box. The black color is compatible with NDS-style and Rain Bird bodies, and the molded overlap seats securely without adhesive or hardware. A cost-effective retrofit solution when a pressure regulator, flow sensor, or additional fittings are added to an existing valve after installation. Eliminates the need to excavate and replace the entire valve box assembly and works with standard large-series lids.
