- PROTECT DRAINAGE SYSTEM: Block debris from entering and potentially clogging the pipeline by using a grate on top of a drain pipe, while still letting excess surface water flow through
- IDEAL FOR MODERATE FLOWS: This drain grate will drain moderate flows from mulched landscape beds, natural areas and window wells
- QUICK, EASY INSTALL: Place on top of a drain pipe or drain pipe fitting for a soil-tight fit; our atrium grates are available in a variety of colors and materials to blend seamlessly with your landscape
- BUILT TO LAST: Made of polyvinyl chloride, the atrium drain grate will withstand weather and temperatures, resistant to cracking and fading
- SPECS: Grate is 4-7/16 in. high; top is 2-3/4 in. diameter; grate openings are ¼ in. wide
When draining moderate stormwater flows from mulched landscape beds, natural areas, window wells, and areas prone to debris, the atrium drain grate rises to the challenge. Unlike a flat grate that lies flush with the surface, the 4 in. Atrium Grate has a raised dome design that blocks leaves, mulch, and other debris near the base, while continuously allowing water to flow through the top. The 4 in. atrium dome drain grate has an open surface area of 21.5 sq. in. and a flow rate of 66 GPM. Connect to 3 in. & 4 in. sewer and drain pipe & fittings, 3 in. & 4 in. single-wall corrugated pipe, and 3 in. & 4 in. triple-wall pipe for a soil-tight fit. Built to stand up to the elements, the drain grate (or drain cover) is made of polyethylene, a type of plastic, using a combination of virgin and recycled content treated with UV inhibitors to prevent fading and cracking from the sun. As part of a complete drainage system, the grate drains water entering drain pipes. The pipes carry the water to a discharge point downstream such as a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench.
