20" Round Catch Basin Kit (7 Hole)

Polylok 20" round catch basins are designed for efficient drainage management in various applications. These catch basins are typically used to collect and redirect water from surfaces such as driveways, sidewalks, and lawns, preventing water pooling and reducing erosion.

These catch basins stand out with their customizable design, allowing you to choose the height of inlets and outlets and incorporate risers to achieve the desired grade or increase capacity. Unique to Polylok, the included seals are designed for effortless installation and accommodate various pipe sizes and pipe types such as SDR 35, SCH 40 and corrugated—an option not available with other brands!
