The Modular Pro Series channel drains are efficient, easy to use and will decrease installation time. They quickly remove water from hardscapes as perimeter drains and direct it away from building structures or any other area requiring surface drainage. The 8" x 20" Deep Profile Channel Drain is made of high impact PVC with mechanical interlocking joints. Ultraviolet light inhibitors are added to prevent fading and cracking from exposure to the sun. The interlocking channel design allows each channel to securely lock to the next for a secure, tight fit.
