Use the Spee-D Channel Drain End Cap to close either end of the Spee-D Channel Drain and direct water flow. The End Cap is made of polyvinyl chloride, a type of plastic, and attaches directly to the channel to seal-no coupling needed; use with solvent-weld glue for a water-tight connection. Spee-D Channel Drains, part of the NDS Profile Channel series, are ideal for draining moderate flows of surface water from driveways, concrete and paver patios, pool areas, courtyards, and walkways to prevent mildew growth, slip hazards, and structural damage. Channel drains, also called trench drains, are long, narrow drains used for surface drainage of hardscapes. As part of a complete drainage system, channel drains collect and convey water to drain pipes, which carry the water downstream to discharge with a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench. NDS channel and trench drains are designed for durability, drainage, and performance, and are a proven alternative to traditional concrete drains.
