Featuring a raised dome that blocks debris while allowing a 66 GPM flow rate through 21.5 sq. in. of open surface, it prevents clogs in mulched beds and natural areas. UV-resistant and easy to install, it’s a professional-grade solution trusted since 1972 to maintain efficient stormwater drainage and protect your landscape investment. ## Description 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. Start now and find the right drainage grate for your project with the free NDS Home Drainage Center tool at ndspro.com/home-drainage. NDS, founded in 1972, is the preferred choice of professionals and the leader in stormwater management solutions with proven products, tools, and support to help you get the job done right. Review: I bought this 4” atrium drain cover to replace an old cracked one in my yard, and it works exactly as expected. The fit was spot on, installation took less than a minute, and it snaps securely in place. The domed design keeps leaves, mulch, and debris from clogging the drain while still letting water flow freely—even during heavy rain. The plastic feels thick and sturdy, not flimsy like some cheaper versions, and it blends in nicely with the landscaping. After a few storms, it’s held up well with no shifting or damage. If you need a reliable replacement for your yard or garden drain, this is a simple, affordable solution that gets the job done.
