The Rain Bird DG6RFB 6" Round Flat Drainage Grate in Black is a no-nonsense, high-performance drainage solution engineered to handle surface water runoff in residential, commercial, and municipal landscapes. Manufactured from structurally foamed High-Density Polyethylene (HDPE) with a built-in UV stabilizer, this grate is built to resist sun degradation season after season without cracking, fading, or warping. Its flat-profile, round design sits flush with the surrounding ground surface — making it virtually invisible once installed and ideal for manicured lawns, patios, driveways, and walkways where appearance matters.
What makes this grate stand out is its precision-engineered compatibility. The DG6RFB features three stepped diameters that allow it to connect directly to 6" Sewer and Drain (S&D) pipe and fittings, 6" Triple Wall Pipe, and 6" Corrugated Pipe — covering the most common drainage pipe types used in landscape and site drainage applications. Large open slots deliver a maximum flow rate of 16 GPM while still blocking large debris from entering the system. The textured anti-skid surface provides secure footing for pedestrians, and the grate is load-rated for pedestrian traffic as well as autos and light trucks traveling at speeds under 20 mph — with a maximum load rating of 1,000 lbs. It is fully ADA compliant and Made in the USA.
This grate is the ideal finishing piece for a Rain Bird 6" Round Catch Basin installation. DripWorks carries the complete Rain Bird drainage line — including catch basins, grates, and complete drainage kits — so you can build a fully integrated surface drainage system from a single trusted source. If a green finish better matches your landscape, the same grate is also available in a Rain Bird DG6RFG Green version.

What pipe types does the DG6RFB connect to?
The DG6RFB features three stepped diameters that allow it to attach directly to 6" Sewer and Drain (S&D) pipe and fittings, 6" Triple Wall Pipe, and 6" Corrugated Pipe — the three most commonly used pipe types in residential and commercial surface drainage systems. No adapters required.
What catch basin does this grate pair with?
The DG6RFB is designed to work as the grate cover for Rain Bird 6" Round Catch Basins available in 1-outlet and 2-outlet configurations. DripWorks carries both. If you need a complete package, browse the full Rain Bird Drainage category for basin kits that include grates, basins, and adapters together.
Is this grate safe for driveways and vehicle traffic?
Yes. The DG6RFB is load-rated for autos and light trucks at speeds under 20 mph, with a maximum load rating of 1,000 lbs. It is also rated for pedestrian traffic. This makes it suitable for installation in residential driveways, parking areas, and walkways in addition to lawn and garden applications.
Is it ADA compliant?
Yes. The flat profile and 5/16" open slot width meet ADA requirements, ensuring the grate is safe for wheelchairs and does not create a tripping hazard for pedestrians. This makes it appropriate for public sidewalks, commercial properties, and municipal applications.
Will this grate fade or crack in the sun?
Rain Bird manufactures the DG6RFB with UV stabilizers built directly into the HDPE material, reducing sun-related degradation over time. The structurally foamed HDPE construction resists cracking and warping under normal outdoor conditions, making it suitable for full-sun installations in hot climates.
Is the green version of this grate available at DripWorks?
Yes. If you prefer a grate that blends into grass or vegetation rather than pavement, the Rain Bird DG6RFG in Green is also available at DripWorks. Both versions share the same specifications, load ratings, and pipe compatibility.
Do I need tools to install this grate?
No special tools are required. The grate simply snaps onto compatible 6" pipe or catch basin. Installation typically takes just a few minutes. The stepped diameters allow it to seat securely without adhesives or fasteners in most standard configurations.
Can I use this grate in a lawn area that receives foot traffic?
Absolutely. The anti-skid textured surface and flat-flush profile make it safe and unobtrusive in lawn settings. Once installed flush with the surrounding grade, it blends into the landscape and poses no trip hazard for pedestrians or interference with lawn mowers.
