NDS Dura Slope Kit with DS-603-BF Cast Iron Tile Grate – BoOF


Pre-sloped decorative system by NDS®.


This kit features the Tile pattern grate for the 6″ Dura Slope by NDS®. 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.  For easy bottom outlet hookup, use 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 ensure straight channel runs, incorporating an integral snap-lock feature that prevents joint movement during channel installation.
