Cast Iron Grates

Our Cast Iron Grates are available for our Rain Drain product, but can be used in other applications. The 9"x13" is the ideal size for the Rain Drain solution. The 9"x9" and 12"x12" were designed for our 9" and 12" square catch basins. Note: Our Polylok cast iron grates are designed to provide durable and long-lasting performance. However, please note that we do not provide a warranty against rust formation. To help prevent rust and extend the life of your grates, we recommend regularly wiping them with a thin layer of oil. This simple maintenance step will help protect your grates and minimize the risk of further rusting.
