The Trex Select Classic Railing Installation Instructions (PDF) provide complete, step-by-step guidance for installing Trex Select® horizontal and stair railing systems. This updated manual covers 6′ and 8′ clear-span railing sections and includes instructions for standard, traditional, and cocktail-style railing applications.
Trex Select Classic Railing is designed for straightforward installation with pressure-treated 4×4 posts or Trex post mounts, and the guide outlines proper post spacing, post sleeve installation, and skirt placement. Installers will find clear diagrams showing where to position brackets, how to align baluster holes, and how to ensure consistent rail height across multiple spans. The manual also details the required use of the Trex aluminum rail stiffener for 8′ spans to meet code requirements.
For standard horizontal railing, the instructions walk through measuring and cutting rail sections, installing foot blocks, attaching top and bottom brackets, inserting balusters, and securing the fully assembled rail between posts. Each step is illustrated to help maintain proper spacing and achieve a level, secure railing section.
The guide also includes full installation procedures for Select cocktail railing—where a deck board serves as the top rail—and traditional railing, which adds a 2×4 lateral top rail for a more dimensional profile. Each style includes cutting requirements, fastening methods, and pre-drilling guidance to prevent splitting.
Stair railing installation instructions cover measuring stair angles, cutting bottom and top rails, attaching stair adaptor brackets, installing balusters on an incline, and ensuring rail height meets code requirements along stair runs. Important notes emphasize using low drill speeds and avoiding impact drivers to protect components.
