Build your custom Slim Channel drainage system using the Slim™ Channel Drain Coupling. The coupling, or coupler, fits inside channel drain components such as channel sections, elbows, and tees and connects them together.
The Slim Channel Drain Coupling is made of polyvinyl chloride (PVC) treated with UV inhibitors. Slim Channels are part of the NDS Profile Series™ Channel, and ideal for capturing light water flows from pool and spa areas, concrete and paver patios, and walkways.
