NDS Mini Channel Drain acts as a perimeter drain, quickly removing water from hardscapes and directing it away from building structures. It is ideal for residential or non-residential applications that anticipate moderate amounts of drainage water and is a low-cost alternative to the NDS Spee-D Channel. The NDS Mini Channel Drain is excellent for light duty applications including pools, patios, spas and tennis courts. It offers a greater surface area than the micro, with brass and a range of colored plastic grates available. Mini Channel Couplings must be used to connect to Mini Channel Fittings.
