The NDS 1 is a 4-inch square plastic drain grate designed for use with 3-inch drain pipe connections. Constructed from green-tinted plastic, this grate fits over standard drain basins and catch bodies to allow surface water to flow through while blocking debris. It is a common component in landscape drainage, yard drainage, and surface water management systems. Plumbers, irrigation contractors, and drainage installers typically specify this grate when completing a ground-level drain installation where a finished, low-profile cover is required.
This grate is suited for residential and light commercial landscape drainage applications. It fits over drain bodies accepting a 3-inch pipe inlet and provides a 4-inch square surface footprint. The green color blends with turf and ground cover, making it a practical choice for lawn, garden bed, and yard drainage installations where a discreet finish is preferred.
Designed as an OEM-style replacement or standard fitment grate for surface drain bodies accepting a 3-inch pipe connection with a 4-inch square grate opening.
Installation is typically performed by plumbers or landscape drainage contractors. Before servicing or replacing a drain grate, ensure the area is clear of standing water and that the downstream pipe is not under active flow. No special tools are required for grate replacement. Follow applicable local plumbing and site drainage codes when installing or modifying surface drainage systems.
