12x12 Catch Basin Dome Grate

For effective stormwater management, installing a catch basin under downspouts in a driveway, parking lot or in high-flow areas is essential. Unlike traditional flat grates, our Dome Grate is designed to prevent clogs by allowing water to flow freely while keeping leaves, debris, and other obstructions out of your system. Its elevated design ensures continuous drainage, even during heavy rainfall, making it a superior solution for both residential and commercial applications.

By upgrading to our Dome Grate system, you enhance water flow efficiency and reduce the risk of blockages compared to traditional flat grates. Easy to install and built to last, it’s the ideal choice for long-term stormwater management.
