4 Atrium Grate Black

The atrium drain grate is the perfect solution for draining moderate stormwater flows from mulched landscape beds, natural areas, window wells, and areas prone to debris. Unlike flat grates that sit flush with the surface, the 4 in. Atrium Grate features a raised dome design that effectively blocks leaves, mulch, and other debris while still allowing water to flow through.

With an open surface area of 21.5 sq. in. and a flow rate of 66 GPM, the 4 in. atrium dome drain grate is compatible with 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. Constructed from polyethylene, a durable type of plastic, the drain grate is designed to withstand the elements, treated with UV inhibitors to prevent fading and cracking from the sun.

This drain grate is an essential component of a complete drainage system, ensuring that water entering drain pipes is properly drained to a discharge point downstream or allowed to percolate into the ground through a dry well or infiltration trench.
