Smooth lines. No visible hardware. Both add to the high-end look of RadianceRail composite railing, TimberTech’s most sought-after railing product. RadianceRail composite railing colors perfectly match or complement all our planks – especially our higher-end planks like XLM and Earthwood Evolutions. Homeowners can mix and match differing post and rail colors, curve the rail and add DeckLites deck lighting system for a truly upscale look that reflects their unique styles. Gates are also available.
