With a robust 12 GPM flow rate and a soil-tight fit, this PVC grate is perfect for various locations, ensuring your drainage system remains clear and efficient. ## Description Keep your drainage system running smoothly with a drain grate that prevents harmful leaves and debris from entering and potentially clogging your pipeline. The 5 in. square drain grate fits right on top of the pipe and is ideal for handling light flows of stormwater from small lawns, landscaped areas, walkways, and patios. The 5 in. Square Drain Grate has an open surface area of 4.3 sq. in. and a flow rate of 13 GPM, ideal for a variety of landscaped areas. Connects to 4 in. sewer and drain pipe & fittings, 4 in. single-wall corrugated pipe, and 4 in. triple-wall pipe for a soil-tight fit. The drain grate, also known as a drain cover, is ADA Compliant and heel-proof. Built to stand up to the elements, it’s made of polyethylene, a type of plastic, using virgin and recycled content treated with UV inhibitors to prevent fading and cracking from the sun. As part of a complete drainage system, the pipe grate drains water and prevents debris from entering drain pipes. The pipes carry the water to a discharge point downstream such as a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench.NDS offers free tools such as the Home Drainage Center, Calculators, and NDS Stormwater Drainage mobile app to help make your project a success. Founded in 1972, NDS is the preferred choice of professionals and the leader in stormwater management solutions. ## Features - BLOCKS LEAVES AND DEBRIS: Protect your drainage system by preventing leaves and debris from entering and potentially clogging the pipeline while letting excess surface water flow through - WORKS IN A VARIETY OF LOCATIONS: Ideal for draining light water flows from small lawns, landscaped areas, walkways and patios - CONNECTIVITY: Fits 4 in. sewer and drain pipes and 4 in. sewer and drain fittings - SOIL-TIGHT FIT: Place drain cover on top of drain pipe or drain fitting; 4 in. round drain grates come in a variety of colors - SPECIFICATIONS: 12 GPM flow rate, 3.9 sq. in. open surface area; meets applicable ASTM standards ## Product Details - **Brand:** NDS - **Color:** White - **Material:** Plastic - **Finish Type:** Polished - **Product Dimensions:** 4.25"W x 1.75"H ## Images ![NDS 9P11, 4-Inch Round Grate, Fits 4-Inch Sewer & Drain Fittings, PVC, White - Image 1](https://m.media-amazon.com/images/I/61Vwh5QPW0L.jpg) ![NDS 9P11, 4-Inch Round Grate, Fits 4-Inch Sewer & Drain Fittings, PVC, White - Image 2](https://m.media-amazon.com/images/I/61X4yflxb6L.jpg) ![NDS 9P11, 4-Inch Round Grate, Fits 4-Inch Sewer & Drain Fittings, PVC, White - Image 3](https://m.media-amazon.com/images/I/617CbxTRiGL.jpg) ![NDS 9P11, 4-Inch Round Grate, Fits 4-Inch Sewer & Drain Fittings, PVC, White - Image 4](https://m.media-amazon.com/images/I/416TGLIQH2L.jpg) ![NDS 9P11, 4-Inch Round Grate, Fits 4-Inch Sewer & Drain Fittings, PVC, White - Image 5](https://m.media-amazon.com/images/I/51aGbXYl3sL.jpg) ## Questions & Answers **Q: how can i connect these drain covers to my 4" sch 40 pvc pipe without buying $20 4" repair couplings (since these are exact size of my pipe)?** A: This drain cover is actually 4.25 inches in diameter per the description. You need to find one that is 4” or a little less. **Q: Does This fit inside 4 inch pvc?** A: no. this drain grate is exactly the same size as 4" sch 40 pvc pipe. so the grate won't fit over or into the pipe. i believe it'll requires a 4" repair coupling. but those cost over $20 ea at our local big hardware store. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as intended *by R***S on November 16, 2024* Bought this to put into the Y-splitter for downspout underground drain pipe, it fit well, looks fine, the price is also acceptable. ### ⭐⭐⭐⭐⭐ Works as attended *by P***F on September 5, 2024* Works great.
