NDS® Mini Channel linear drain is a non-sloped system built for light traffic applications such as pools, patios, and walkways. The channel is UV-protected and manufactured from durable lightweight polyolefin plastic. This kit includes the heelproof and ADA-compliant TDS Bronze Age™ ductile iron grate in the Rain Drop pattern with a painted black finish (for shipping purposes only).


Available online in 6, 12, 18, and 24-foot kits; custom system lengths are available. Request a Quote.


The 3ft Extension and the 6ft Extension kits are intended to be an extension to the standard length kits and do not include the end cap/outlet. Other accessories are to be purchased separately if intended to be a stand-alone kit.
