Trex Trough 12ft

The Trex Trough 12ft is an essential part of the Trex RainEscape® under-deck drainage system. Its main job is to channel rainwater and snowmelt away from your deck joists, guiding it into downspouts and out from underneath your deck. This keeps the area below dry, opening up new possibilities for an outdoor living space complete with furniture, lights, and even ceiling fans.

Each Trex Trough measures 12 feet in length, making it ideal for mid-sized decks or areas where shorter runs are needed. Built from durable, waterproof material, it provides reliable protection against heavy rain, snow, and extreme temperature changes. By preventing water from soaking your deck framing, the trough helps extend the life of your deck and reduces costly repairs.

Lightweight and flexible, the Trex Trough 12ft is easy to handle and quick to install. It fits neatly between deck joists and works with Trex RainEscape downspouts and tape for a complete watertight system. For contractors, it speeds up installation and ensures long-lasting performance. For homeowners, it transforms the space under your deck into a dry, comfortable retreat.
