Stormwater happens. But when all that surface water floods its surroundings and lingers, it can erode the soil and create costly water damage. The 18 in. Round Drain Grate helps preserve property by draining away heavy flows of runoff from lawns, landscaped areas, parks, and courtyards. It also keeps leaves and debris from getting into your drainage system, preventing clogs. Features an open surface area of 75.6 sq. in. and flow rate of 231 GPM.
The 18 in. Round Grate connects to the 18 in. sewer and drain fittings and 18 in. single-wall corrugated pipe for a soil-tight fit. Made of polypropylene (PP) treated with UV inhibitors.
