NDS® Dura Slope Kit with DS-601-BF Cast Iron Weave Grate – BoOF


Pre-sloped decorative system by NDS®.


This kit features the Weave pattern grate for the 6″ Dura Slope by NDS®. A lightweight HDPE drainage system, NDS Dura Slope sets high chemical and load resistance standards. Its four-foot modular channel sections offer a 0.7% slope with a rounded bottom, creating an efficient water evacuation route for any application. Each channel has a 4″ bottom outlet knockout that provides greater design variability for the drainage system.  For easy bottom outlet hookup, use the DS-126 Bottom Outlet Adapter.

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 ensuring straight channel runs, incorporating an integral snap-lock feature that prevents joint movement during channel installation.
