Designed to be as beautiful as they are functional, NDS plastic decorative grates are ideal for any application and come in a range of colors and designs, which aesthetically blend into any outdoor area. In combination with the lightweight, easy-to-install channel drains the need for grading a deck surface to a low area is eliminated, as the system acts as a perimeter drain with flow rates above 14%. Designed for long-term enjoyment, all plastic components are chemically resistant and have UV inhibitors to prevent fading and cracking from the sun.
