Visit www.timbertech.com/installation to view TimberTech installation videos.
Consult your local building codes for guard and handrail requirements.
RadianceRail® is available in 10’, 8’, and 6’ lengths.
Measuring Your Railing Area
• Measurements are from center to center of the posts. Rails
are produced in 10’, 8’, and 6’ lengths to allow for finished
end cuts and angles.
• Determine how many 10’, 8’, and 6’ RadianceRail sections
you need and check to be sure you have all the components
(and quantities) listed in the chart shown to the right.
Important Information
• RadianceRail 10’, 8’, and 6’ Rails are designed not to exceed
10’, 8’, and 6’’ center of post to center of post, respectively.
• For stair applications maximum rail length must not exceed 91”
• Cut slowly, using a fine tooth saw blade to avoid chipping.
• For 42” railing use 12’ Post Sleeves.
• Custom Rail Packs should be used when installing Aluminum
Balusters.
