Molded from polyethylene using a blend of virgin and recycled content, the grate incorporates UV inhibitors to resist fading and cracking under prolonged sun exposure. It measures 4.5 inches in diameter and 1.5 inches in height, weighs 1.0 pound, and delivers an open surface area of 2.4 square inches with a rated flow rate of 7 gallons per minute. The green matte finish blends into landscaped settings. This grate is ADA compliant and heel-proof, meeting common site accessibility requirements without additional hardware.\u003c\/p\u003e\n\u003cp\u003eThe NDS 13u is suited for draining small lawns, landscaped beds, patios, and walkways where light stormwater collection is needed. It connects to 3 inch and 4 inch sewer and drain pipe fittings, 3 inch and 4 inch single-wall corrugated pipe, and 3 inch and 4 inch triple-wall pipe for a soil-tight fit. As part of a complete drainage system, the grate feeds collected water downstream to a discharge point such as a pop-up emitter, a dry well, or an infiltration trench. Typical installers include landscape contractors, irrigation technicians, and experienced DIYers working on surface drainage projects.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFits 3 inch and 4 inch sewer and drain pipe, single-wall corrugated pipe, and triple-wall pipe\u003c\/li\u003e\n  \u003cli\u003eADA compliant and heel-proof construction\u003c\/li\u003e\n  \u003cli\u003eUV-inhibited polyethylene resists fading and cracking from sun exposure\u003c\/li\u003e\n  \u003cli\u003e7 GPM rated flow rate with 2.4 square inches of open surface area\u003c\/li\u003e\n  \u003cli\u003eRated to 140 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eGreen matte finish blends into turf and landscape environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConnects to 3 inch and 4 inch sewer and drain pipe fittings, 3 inch and 4 inch single-wall corrugated pipes, and 3 inch and 4 inch triple-wall pipes for a soil-tight fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLandscape contractors and plumbers typically install this grate as the final surface component of a buried drain pipe run. Ensure the pipe end is clean and free of debris before seating the grate. No special tools are required, but confirm the pipe size matches the grate before installation to maintain a soil-tight connection. Follow all applicable local stormwater and plumbing codes when routing the downstream pipe to a discharge point.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Size (Minimum)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Pipe Size (Maximum)\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 7 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpen Surface Area\u003c\/strong\u003e: 2.4 square inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Width\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Depth\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Height\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.0 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyethylene plastic (virgin and recycled content)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\/Finish\u003c\/strong\u003e: Green\/Matte\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrate Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Size\u003c\/strong\u003e: 1\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: 13u\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDS","offers":[{"title":"Default Title","offer_id":51620772970802,"sku":"13U","price":15.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/02fdc105a20590ca3903f4cc52be7a13.jpg?v=1787346259","url":"https:\/\/voomisupply.com\/products\/nds-13u-round-drainage-grate-green-3-4-inch-pipe","provider":"Voomi Supply","version":"1.0","type":"link"}
