NDS 4 in. Round Grate, Fits 4 in. Sewer & Drain Fittings, White HIPS (911)

About This Product
The 4 in. Round Drain Grate helps manage light flows of excess surface water while blocking leaves and debris from entering the drainage pipeline. It's perfect for use on patios, decks, and around pools to prevent water damage. With a 3.9 sq. in. open surface area and a flow rate of 12 GPM, this drain grate connects to 4 in. Sewer and Drain (S&D) fittings, such as an adapter, to ensure a secure connection to drain pipes. Made of high-impact polystyrene (HIPS) treated with UV inhibitors, this grate is designed for non-pressurized underground applications, with a maximum working pressure of 5 psi. NDS provides free tools, such as the Home Drainage Center, Calculators, and the NDS Stormwater Drainage mobile app, to help you with your project.
