When you need to drain excess surface water before it does property damage, you don’t need those pesky leaves and debris getting in the way. The 4 in. Round Drain Grate blocks these intruders from entering and potentially clogging the pipeline. Open surface area of 3.9 sq. in. and flow rate of 12 GPM, it is ideal for draining light flows of stormwater from small lawns, landscaped areas, patios, and walkways.
The 4 in. Round Grate connects to 4 in. sewer and drain pipe & fittings, 4 in. single-wall corrugated pipe, and 4 in. triple-wall pipe for a soil-tight fit. Made of high-density polyethylene (HDPE) treated with UV inhibitors. H
