Dura - Valve Box - 15X21 Rct Large Lid Only Elect Junct Gry

This grey electrical-junction-designated lid for the large rectangular valve box clearly marks underground chambers housing low-voltage wiring splices or irrigation control wiring, helping field technicians identify box function without opening each unit.
Overview The grey color is widely used in the landscape irrigation industry to designate boxes that contain wire junctions rather than valves, reducing service time and the risk of inadvertently cutting irrigation wires during valve maintenance. The UV-stabilized polyethylene construction ensures the lid retains structural integrity in direct sunlight. Fits all standard 15� x 21� large rectangular valve box bodies. A critical safety and organization tool on commercial and multi-zone residential systems where multiple box types are installed in proximity. Hand-removable for quick access.
