Protect and extend access to irrigation and utility components with the NDS 113-6 Standard Series valve box extension. Designed for contractors and long-term outdoor use, this black rectangular riser nests into a 14 x 19 in. valve box to raise the access area while keeping components concealed and protected.

  • Compatibility: Fits 14 x 19 in. rectangular valve boxes; nests to add usable access height for shallow installations.
  • Dimensions: 14 in. x 19 in. body with a 6-3/4 in. overall height; provides approximately 6 in. of additional access when nested.
  • Durable construction: Made of polypropylene treated with UV inhibitors to resist discoloration and weathering in outdoor environments.
  • Reinforced strength: Structural reinforcing ribs and a double wall at the cover seat improve sidewall and top support for heavier loads.
  • Bolt-down capability: Designed with a bolt hole and a 3/8" nut provision for secure fast mounting when required.
  • Landscape-friendly design: Overlapping top design prevents dirt and grass from settling between body and cover.

Easy to install, the 113-6 extension can be used alone for shallow protection or stacked onto a matching 14 x 19 in. valve box to create greater depth for isolation valves, manifolds, or drip components. Built for professional and residential irrigation systems, it offers a balance of lightweight handling and structural durability for long service life.
