NDS Dura Slope Trench Drain Sections

Product Details: NDS Dura Slope Trench Drain Sections

The NDS Dura Slope trench drain system consists of neutral and pre-sloped sections of the trench drain. Manufactured from High-density polyethylene (HDPE), this trench drain offers a durable alternative to concrete channels that will save time and reduce cost at installation. Each 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. NDS Dura Slope features a "ProFit" locking system that locks the grate to the integral frame and supports the trench drain during installation. Dura Slope Trench Drain also features DuraLoc, an integral joint lock that prevents joint movement during installation, no extra clamps or screws are needed. It includes interlocking tongue and groove joints and bottom outlet on each channel section and should be used in non-residential applications.

Quick Look

Dura Slope Channel and grates have been tested to the AASHTO M-306 and EN 1433 (DIN 1958) test methods by an independent AASHTO accredited lab
Class B (65-175 PSI) Load Rated
Dura Slope Channel can make bends as small as 30” radius using the Dura Slope Radius Couplings
Heel-Proof Grate Options
194 feet of continuous slope; 266 feet with neutral sections added
The channels must be installed in ascending numerical order starting with the smallest part number. The part number sticker also shows the number of the segment to be installed upstream and downstream of segment
The shallowest channel is 3.99” from the bottom of the grate to the flow line in the channel. The deepest channel is 12.06” from the bottom of the grate to the flow line
Interlocking tongue and groove joints for secure alignment and easy installation
ADA Compliant
The fall in each sloped section of Dura Slope channel is 0.34”. Each section comes with a builtin 0.7% slope. The neutral sections have flat bottoms
Manufactured in the U.S.A
Channel Sizes: 48" length, 6" width, 3.998" to 12.062" inner depth range
If connecting to 4” sewer and drain (SDR35) pipe, cut out the bottom drain and insert the DS126 Bottom Outlet Adapter. If using 4” schedule 40 pipes, connect NDS part # 56-44 flexible coupling to the 4” pipe and then to the bottom drain of the channel. Tighten the clamps to secure in place
Other diameter pipes can be connected using the appropriate flexible coupling
All Dura Slope Channels come with a removable cover. Put tape over the slots and screws prior to pouring concrete. After concrete has been finished and cured, remove and discard the covers
The screws are used to secure the grates to the channel
75-396 GPM
Manufactured from molded, structural foam HDPE with UV inhibitors
Product Class: 25DS
Without the use of neutral sections (no bottom slope), the maximum length run is 96 feet. With the use of one neutral section in its designed place, the maximum length run is 132 feet
NDS does not recommend connecting more than 4 consecutive neutral segments together to allow for proper flow and prevent standing water in the channel
