Trex Trough 16ft

The Trex Trough 16ft is a key component of the Trex RainEscape under-deck drainage system. Designed to divert water away from your deck, the trough channels rain and snowmelt into downspouts, keeping the area below your deck dry and usable. This makes it possible to create an outdoor living space under your deck, complete with lighting, ceiling fans, and furniture, without worrying about leaks.

Each Trex Trough measures 16 feet in length, making it ideal for covering longer deck spans with fewer seams. Made from high-quality, waterproof material, it is engineered to withstand heavy rain, snow, and temperature extremes. When properly installed, the Trex Trough 16ft provides a reliable, watertight seal that protects your deck framing from moisture damage and extends the life of your deck.

The Trex Trough 16ft is lightweight, flexible, and easy to install. It fits neatly between deck joists and works in combination with Trex RainEscape downspouts and tape to create a complete drainage solution. For contractors, it saves installation time and reduces callbacks. For homeowners, it adds long-term value by transforming unused space into a functional outdoor retreat.
