NDS Spee-D 101 6" Black Round Catch Basin Drain, 1 Outlet helps prevent costly property damage by providing an effective way to drain. The Spee-D® Catch Basin drain works with a drain grate (sold separately) to collect water from flood-prone areas such as lawns, landscaped areas, patios, and walkways, and direct the water to drain pipe. Use the 1-outlet stormwater catch basin alone or to start a series of connected basins positioned downstream. Basin outlet with locking flex tabs connects to 3 in. & 4 in. single-wall corrugated, sewer and drain, and triple-wall pipes, and 4 in. Sch. 40 pipe. Made of high-impact polystyrene (HIPS) treated with UV inhibitors. Basin sump area collects debris and is easily accessible to clean. Hassle-free limited lifetime warranty guarantees the NDS product is free from defects—or we’ll replace it.
