Professional Surface Drainage. ADA Compliant. Built to Last.
The Rain Bird DG6RFG 6″ Round Flat Drainage Grate is a rugged, USA-made drainage solution designed for residential, light commercial, and municipal applications where water runoff needs to be controlled quickly and reliably. Manufactured from structurally foamed High-Density Polyethylene (HDPE) with a built-in UV inhibitor, this grate resists sun degradation season after season — making it equally at home in sun-baked California landscapes, rainy Pacific Northwest yards, or the humid Gulf Coast.
What sets this grate apart is its combination of high-flow capacity and safety-first design. The large-opening slots deliver a maximum flow rating of 16 GPM, yet the 5/16″ slot width prevents large debris from entering and clogging your drainage pipe. The textured anti-skid surface and ADA-compliant profile make it safe for foot traffic in walkways, driveways, and turf areas. With a load rating of 1,000 lbs — including autos and light trucks traveling at speeds less than 20 mph — this grate can handle the demands of driveways and parking areas without issue.
Installation is straightforward: the grate features three stepped diameters that allow direct attachment to 6″ Sewer & Drain (S&D) Pipe (ASTM D2729 / ASTM D3034 SDR 35), 6″ Triple Wall Pipe, and 6″ Corrugated Pipe — no adapter needed in most applications. It is also compatible with the Rain Bird DB6R1 6″ Round Drainage Catch Basin, making it easy to build a complete surface drainage system. For areas where a round profile isn’t ideal, Rain Bird’s drainage line also includes square basin and grate options available in the DripWorks Drainage Category.
All Rain Bird drainage products — including this grate — are constructed from 100% recycled plastic, qualifying them for points on LEED-certified projects. If you’re managing stormwater on a green-building or sustainable landscaping project, this is a smart, spec-ready choice.
