Got lots of mulch and debris in the area you're draining? The 4 in. Atrium Drain Grate is designed for the job. The domed design rises above the surface of the ground to block leaves, mulch and other debris near the base of the drain grate, while letting stormwater drain from the above. Use in mulched landscape beds, natural areas, and window wells to drain moderate flows of excess stormwater. The 4 in. atrium dome drain grate has an open surface area of 17 sq. in. and a flow rate of 52 GPM. Connect to 4 in. sewer and drain pipe fittings, 4 in. single-wall corrugated pipe, and 4 in. triple-wall pipe for a soil-tight fit. Built to stand up to the elements, the atrium drain grate 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 pipe 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.

Features: Protect your drainage system by using a grate on top of drain pipe to block debris from entering and potentially clogging the pipeline while letting excess surface water flow through Ideal for draining moderate water flows from mulched landscape beds, natural areas, and window wells Fits 4 in. Sewer and Drain Pipe Fittings, 4 in. Single-Wall Corrugated Pipe, 4 in. Triple-Wall Pipe 17 sq. in. open surface area 52 GPM flow rate Atrium design offers enough open surface area to allow water to flow freely in areas that are prone to debris collection Grate is 4-7/16 in. high; top is 2-3/4 in. wide in diameter; grate openings are OE in. wide 4 in. Atrium Drain Grates are available in a variety of colors and materials Comes with one 4 in. Atrium Grate Works with connected drain pipe to capture and convey excess surface water for proper release downstream Place on top of drain pipe or drain fitting for a soil-tight fit High-density polyethylene (HDPE) using a combination of virgin and recycled content treated with UV inhibitors to prevent fading and cracking Use sewer and drain fittings when you need to make turns from the drain grate to drain pipe Use with a Pop-Up Drainage Emitter to discharge collected water at a point of release downstream Use with a Flo-Well Dry Well System and EZ Drain Gravel-Free French Drain System to detain excess water and slowly release it into the ground Onsite stormwater management protects the watershed downstream, and limits excess runoff which can lead to negative impacts such as erosion, pollution, and flooding Founded in 1972, NDS is the preferred choice of professionals and the leader in stormwater management with proven products, tools, and support to help you get the job done right Landscapes Compatibility Chart
