The NDS 74S 3inchSand FLT Atrium Grate protects landscape beds, window wells, and low-flow surface areas. Its domed design keeps leaves and mulch out of the line while allowing stormwater to pass through. It fits 3" sewer & drain pipe and fittings, 3" single-wall corrugated pipe, and 3" triple-wall pipe.
The 74S Atrium Grate provides a maintenance-free alternative to heavier cast or concrete covers. Use it to protect inlet openings, reduce clogging, and keep landscape surfaces clean while ensuring reliable drainage performance.
