The NDS 317C is a professional-grade green jumbo valve box lid designed to provide secure, weather-resistant access to in-ground irrigation and utility valve installations. Measuring 13 x 20 inches, this lid fits jumbo-size valve boxes commonly used in commercial landscape, municipal, and large-scale residential irrigation systems. The green color blends with turf and groundcover, keeping installations low-profile. Irrigation technicians and landscape contractors install this lid as a replacement or upgrade on existing jumbo ICV-style valve boxes where the original cover has cracked, faded, or gone missing.
This lid is suited for use in commercial and residential irrigation valve installations where a jumbo-footprint box is required to house multiple valves or larger inline control valves. It is a common service item for irrigation professionals maintaining drip, spray, and rotor-based systems in parks, golf course rough areas, commercial properties, and residential estates. The professional designation indicates a heavier-duty construction than standard residential lids, making it appropriate for areas subject to foot traffic or mowing equipment.
Designed as an OEM-style replacement lid for NDS jumbo ICV-series valve boxes requiring a 13 x 20 inch cover opening.
Irrigation technicians should shut off the irrigation controller and depressurize the line before opening or replacing a valve box lid in an active system. Lid replacement requires no special tools — seat the lid squarely on the box frame and confirm it is fully engaged before backfilling or restoring turf cover. Follow all applicable local codes for underground utility access covers in pedestrian or vehicle-traffic areas.
