NDS 1211G* Square Catch Basin Drain Grate, Diamond Design, Fits 12-Inch Catch Basin Drain, Risers and Low Profile Adapter, 12-Inch, Plastic, Black

Meet the drain grate, the guardian of your drainage system. Place on top of a catch basin drain, riser, or low-profile adapter, and it defends drain pipes by blocking potential intruders such as dirt, leaves, and debris as it drains heavy flows of stormwater from lawns, landscaped areas, under downspouts, and away from patios and walkways. Drain grates, also known as drain covers, help keep your drain pipes clog-free and running smoothly. The 12x12 drainage grate, as part of a complete drainage solution, works with 12 in. catch basins, low-profile adapters, and risers that are connected to drain pipes to 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. The 12 in. drain grate is made of polyethylene, a type of plastic, treated with UV inhibitors prevent cracking and fading in the sun. Strategic openings on the 53.1 sq. in. open surface area provide 162 GPM flow rate capacity. The storm drain grate is rated for NDS Class B loads when properly installed and is ADA compliant. 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 with proven products, tools, and support to help you get the job done right.
