Adjust the inlet or outlet height of drain pipe connected to your Spee-D Channel Drain system with the Spee-D Channel Drain Offset End Outlet. Twist the off-center outlet to set desired height. Connects to 3 in. sewer and drain pipe & 4 in. sewer and drain fittings. Made of polyvinyl chloride, it can be solvent-welded with PVC glue for a water-tight connection. The Spee-D Channel Drain, part of the NDS Profile Channel series, is ideal for capturing moderate water flows from driveways, patios, pools areas, courtyards, and walkways to prevent slippery mildew, concrete staining, and costly structural damage. Channel drains, also called trench drains, are long, narrow drains that collect water from surrounding surfaces and direct it away to drain pipe. The water is carried to a discharge point downstream such as 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.
