The NDS 111C is a replacement 10 in. round overlapping lid designed for Standard Series valve boxes. Molded for durability and UV resistance, this green lid keeps irrigation control valves and fittings protected from debris, lawn care equipment, and weather while allowing easy service access.

  • Durable construction: Made from UV-stabilized high-density polyethylene (HDPE) with a blend of virgin and recycled content for long-term outdoor performance.
  • Overlapping design: Overlap edge prevents dirt and grass from collecting between lid and box, reducing maintenance and improving longevity.
  • Secure mounting: Includes a bolt hole and nut receptor so the lid can be bolted down (bolt sold separately) for added security.
  • Easy access: Two finger indentations and a bayonet-style twist-fit allow quick removal and reinstallation for routine irrigation service.
  • Compatibility: Fits NDS Standard Series 10 in. round valve boxes (works with 111B/111BC-style bodies and similar Standard Series boxes).
  • Application: Ideal for residential and light-commercial irrigation systems to protect valves, zone kits, and fittings.

Install the 111C lid as a direct replacement or spare for Standard Series 10 in. round boxes to keep irrigation components concealed, secure, and protected. Minimal maintenance is required—clean debris as needed and inspect the bolt hole and lid edge periodically for proper seating.
