When stormwater engulfs mulched areas and needs draining, it’s the atrium drain grate rather than the flat drain grate that’s fit for the job. The 4 in. Brass Atrium Drain Grate has a domed design that rises above the surface of the ground to block leaves, mulch, and other debris near the base of the grate while letting water drain in from above. Has an open surface area of 10.2 sq. in. and flow rate of 31 GPM. Put it to work in mulched landscape beds, natural areas, and window wells to drain moderate flows.
The 4 in. Atrium Grate fits 4 in. sewer and drain pipe & fittings for a soil-tight fit. Made of weather-resistant brass.
