The Rain Bird DG12SFG 12" Plastic Square Flat Drainage Grate (Green) is a professional-grade landscape drainage component engineered to handle serious water flow in residential, commercial, and municipal applications. Manufactured from structurally foamed High-Density Polyethylene (HDPE) with a UV stabilizer to resist sun degradation, this grate is built to perform season after season — from California's rainy winters to the drainage challenges of the Pacific Northwest, the Gulf Coast, and the Southeast.
Designed for maximum performance, the DG12SFG features large open slots (7/16" wide) across a 53 sq. in. open surface area that allow water to flow through quickly while keeping large debris out of your drainage system — making it ideal for areas prone to floating debris. A textured anti-skid surface keeps it safe underfoot, and it's rated to handle up to 3,000 lbs. of load, making it suitable for driveways, parking areas, and pathways where autos and light trucks may pass at speeds under 20 mph. It is also fully ADA compliant for accessible public and commercial spaces.
This grate is compatible with Rain Bird 12" Square Catch Basins and 12" Square Low-Profile Basins. Two integrated screw holes allow it to be secured to the basin using #6 1.5" Phillips flat head stainless screws (not included), preventing vandalism or displacement. For a complete drainage installation, pair this grate with the Rain Bird 12" Square Drainage Catch Basin or grab everything you need in one package with the Rain Bird 12" Drainage Basin Kit with Green Grate and Adapters. If you need a round grate option, DripWorks also carries the Rain Bird 6" Round Flat Drainage Grate and a black color version of this same 12" square grate for areas where green blends naturally into turf.

What catch basins is this grate compatible with?
The DG12SFG is designed to fit Rain Bird's 12" Square Catch Basins and 12" Square Low-Profile Basins. DripWorks carries the Rain Bird 12" Square Drainage Catch Basin (2 Outlets) as a direct companion product. You can also purchase the complete Rain Bird 12" Drainage Basin Kit with Green Grate and Adapters if you want everything bundled together.
Can I drive over this grate?
Yes. The DG12SFG is load-rated at 3,000 lbs., which is sufficient for autos and light trucks traveling at speeds under 20 mph. It is appropriate for use in residential driveways, parking areas, and paved walkways. It is not rated for heavy commercial vehicles or high-speed traffic.
Is this grate ADA compliant?
Yes. The DG12SFG meets ADA accessibility requirements. Its slot width (7/16") and flat profile prevent wheelchair wheels and cane tips from catching, making it safe for installation in accessible public or commercial spaces such as sidewalks, plazas, and entryways.
How is the grate secured to the basin?
The grate includes two screw holes to allow it to be fastened directly to the catch basin. Use #6 × 1.5" Phillips flat head stainless steel screws (sold separately). Securing the grate helps prevent vandalism, displacement by flooding, and accidental removal.
Will this grate hold up outdoors in sun and weather?
Yes. The grate is manufactured from structurally foamed HDPE with a built-in UV stabilizer to resist sun-induced degradation. HDPE is highly resistant to moisture, chemicals, and temperature fluctuations, making it well-suited for year-round outdoor use in any climate — from the wet winters of the Pacific Northwest to the intense sun of the Southwest and Southeast.
Is there a black version of this grate?
Yes. DripWorks carries the Rain Bird DG12SFB 12" Square Flat Drainage Grate in Black — identical in specifications but in a darker color finish that works well in hardscape, concrete, and paved-surface applications.
What is the maximum flow this grate can handle?
The DG12SFG is rated for a maximum flow of 70 GPM through its 53 sq. in. of open surface area. The large slots allow water to pass rapidly during heavy rainfall events while still keeping out leaves, gravel, and other large debris that could clog your drainage pipe.
What pipe sizes does the Rain Bird catch basin connect to?
The Rain Bird 12" Square Catch Basin (sold separately) is designed to connect to 3" and 4" drain pipe using compatible adapters. The Rain Bird 12" Drainage Basin Kit includes both the basin and the necessary adapters for a complete installation.
