Heavy flows of stormwater are no match for the 15 in. Round Grate. Built to handle the heaviest flows from lawns, landscaped areas, parks, and courtyards to prevent soggy lawns and soil erosion. Grate has an open surface area of 85.6 sq. in. and flow rate of 262 GPM. Drains water through while blocking leaves, twigs, and other debris from entering and potentially clogging the pipeline.
The 15 in. Round Grate connects to the 15 in. sewer and drain fittings and 15 in. single-wall corrugated pipe for a soil-tight fit. Made of high-density polyethylene (HDPE) treated with UV inhibitors.
