The 6″ Dura Slope by NDS is one of the most customizable plastic trench drains available for commercial projects. A lightweight HDPE drainage system, NDS Dura Slope sets high standards for chemical and load resistance. Its four foot modular channel sections offer 0.7% slope with rounded bottom, creating an efficient water evacuation route for any application. Each channel has a 4″ bottom outlet knockout that provides a greater degree of design variability for the drainage system.
Dura Slope™ channels are designed with the pre-installed ProFit™ locking system, which maintains structural integrity during installation and locking devices for the grating. LeveLoc™ integral re-bar supports are located at 24” intervals along each side of the channel and contain an internal protruding knob designed to grip #3 or #4 re-bar (3/8” – 1/2”) for easier channel height adjustment during installation. DuraLoc™ tongue and groove ends connect allowing for a precise fit and ensure straight channel runs, incorporating an integral snap-lock feature that prevents joint movement during channel installation.
For heavy trucks or fork truck traffic, we recommend adding the ductile iron frames to your kit.
