RadianceRail, TimberTech's most popular composite deck railing system, is easy to install and creates an upscale look for your outdoor space. The unique bell shape of the RadianceRail Top Rail delivers a smooth beveled edge for high graspability along the sides as well as a flat top surface perfect for resting against or setting down a drink on a warm afternoon. The durable and organic-looking composite material is highly resistant to mold and mildew to prevent any rotting, splintering or warping for decades to come.

TimberTech RadianceRail Top Rail by AZEK is sold individually and is available in 6 foot or 8 foot lengths in the premium TimberTech finishes of White and Black.

Both classic and customizable, AZEK/TimberTech's RadianceRail allows you to choose the color and design of your deck railing design piece by piece.

Please note: you also need the Universal Rail Pack and balusters or another infill to complete a rail section. You can find a full RadianceRail Kit here.
