It is designed for surface drainage applications where a secure, weather-resistant cover is needed over a drain inlet. The open surface area measures 3.85 square inches, providing a flow capacity of 5.04 gallons per minute (GPM). Licensed plumbers and drainage contractors install this grate as part of residential or commercial site drainage systems. Its load rating supports pedestrian, bicycle, and wheelchair traffic, making it appropriate for walkways, patios, and accessible routes.\u003c\/p\u003e\n\u003cp\u003eThis grate fits 4-inch sewer drain pipe fittings, 3-inch corrugated pipe, and 4-inch triple wall pipe. It is suited for outdoor drainage installations where surface runoff must be directed into an underground drainage system. Common applications include landscape drainage, hardscape drainage, driveway borders, and ADA-accessible walkway areas. The black finish blends with standard hardscape materials and resists fading through UV-inhibitor treatment in the polyolefin substrate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch round profile fits standard 4-inch sewer drain fittings, 3-inch corrugated pipe, and 4-inch triple wall pipe\u003c\/li\u003e\n  \u003cli\u003eStructural foam polyolefin construction with UV inhibitors for outdoor durability\u003c\/li\u003e\n  \u003cli\u003e3.85 square inch open surface area with a 5.04 GPM flow rate\u003c\/li\u003e\n  \u003cli\u003eRated for pedestrian, bicycle, and wheelchair traffic loads\u003c\/li\u003e\n  \u003cli\u003eBlack finish resists UV fading in exposed installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eFits 4-inch sewer drain pipe fittings, 3-inch corrugated pipe, and 4-inch triple wall pipe as stated by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed plumber or drainage contractor as part of a subsurface drainage system. Power or water supply to the drainage system area should be confirmed clear before trenching or fitting work begins. Ensure the drain body is fully seated and secured before placing the grate to prevent shifting under traffic loads. Follow local plumbing codes and applicable IPC guidelines for drain placement and cover load requirements.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Structural Foam Polyolefin with UV Inhibitors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Surface Area\u003c\/strong\u003e: 3.85 square inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 5.04 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTraffic Rating\u003c\/strong\u003e: Pedestrian, Bicycle, Wheelchair\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NDS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDS","offers":[{"title":"Default Title","offer_id":51524635459890,"sku":"11","price":77.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7551773713c3c4b1658e55bd85f99d34.jpg?v=1785453635","url":"https:\/\/voomisupply.com\/products\/nds-11-4-inch-black-round-drain-grate","provider":"Voomi Supply","version":"1.0","type":"link"}
