Surface water that remains on hardscapes is not only a slip hazard, it also contributes to mildew growth, concrete staining, and costly water damage. The Slim™ Channel Assembly drains away light flows around pool and spa areas, concrete and paver patios, and walkways. Installation is made easier with sand-colored slotted polypropylene grates preassembled on the polyvinyl chloride channel. Material is treated with UV inhibitors. Slim Channels are part of the NDS Profile Series™ Channel.
