What pieces make up the Trex RainEscape Deck Drainage System?
Maximize your living space with the Trex RainEscape Deck Drainage System. Trex RainEscape is a unique under-deck drainage system that uses a combination of troughs and gutters to keep rail, spills, and snow melt from dripping through elevated deck boards. The Trex RainEscape Deck Drainage System creates a dry space that is perfect for lighting, ceiling fans, lounging systems, and more!
It is installed on the deck joists underneath the deck boards, so is typically installed during the deck build. The system can be installed using caulk, tape, and staples. It is designed to be easily installed by any DIY-er or builder. Trex RainEscape protects against rot by keeping floor joists dry and can be adjusted to fit both standard and non-standard joist spacing.Shop Trex RainEscape
