The NDS® Dura Slope™ trench drain system consists of neutral and pre-sloped sections of trench drain. Manufactured from HDPE, this trench drain offers a durable alternative to concrete channel that will save time and reduce cost at installation. The Dura Slope™ trench drain system consists of lightweight, modular sections for easier handling and installation and reduced freight to the site. A built-in slope of 0.7% allows optimal flow rates to be maintained system wide; neutral sections are also available. The NDS® Dura Slope™ features a ProFit locking system that locks the grate to the integral frame and supports the trench drain during installation. It also features DuraLoc, an integral joint lock which prevents joint movement during installation, no extra clamps or screws needed. It includes interlocking tongue and groove joints and bottom outlet on each channel section and should be used in non-residential applications.
