NDS Dura Slope

Typical Applications

Driveways
Kennels
Sidewalks
Parking Lots

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 neutral and 0.7% slopes with rounded bottoms, 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 hook together without couplers, eliminating the need for small parts while giving the finished drain a neater, straighter appearance. A Dura Slope catch basin (6.25″ x 24″ x 24″) with trash basket is a popular accessory for many Dura Slope drainage systems.

EZ Track

The Dura Slope product line includes EZ Track Radius couplings. EZ Track radius couplings are designed for running track or poolside installations and are used with neutral or pre-sloped Dura Slope channel sections. Each radius coupling allows 3 degrees of motion between trench drain sections, making an adjustable radius easily achievable. The drain radii that can be achieved with the EZ Track coupling are between 80′ and 120′. Each coupling is supplied with an associated “mini grate section” that is made of plastic or ductile iron.
