NDS Dura Slope Kit with DS-604 Cast Iron Brick Grate | Baked on Oil Finish


Pre-sloped decorative system by NDS®.


This kit features the Brick 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.
