TimberTech offers a flat, continuous top rail, uninterrupted by posts and a flat surface with the addition of the Evolutions Rail. Choosing between the contemporary or builder styles means choosing between a minimalist style with three infill options or an affordable alternative with a metal baluster infill. Compatible with the DeckLites system, the rail kits include top rail, bottom rail and mounting hardware. They are available in brick, traditional walnut and class black color options, as well as standard 6-ft. and 8-ft. sections with 36-in. or 42-in. rail heights.
