NDS Slim Channel

Smaller than the Mini Channel and bigger than the Micro Channel!

The grates are replaceable making this plastic trench drain system ideal for residential and light commercial projects.

The NDS Slim Channel system is a 2.25″ robust extruded PVC channel drain designed for residential and light commercial projects. It is ideal for swimming pools, spas, patios and paver landscape applications. The installed height of the channel with grate is 3.125″. However, if anchor clips are being used, add .125″.

Slim Channel is available in 6′ and 9′ lengths. Couplers are designed to provide a seamless run with a secure channel to channel connection. End caps provide the opportunity for a 1.5″ SCH 40 pipe outlet through an integrated knockout. Anchor clips easily twist into place to secure the channel to a prepared base or suspend it with rebar. Bottom outlets can be installed anywhere along the channel for 1.5 SCH 40 pipe connections.
