Description

This post sleeve slides over a 4×4 wood post or structural post to create the foundation of a Trex Railing System. The 6x6 profile gives your posts a traditional, substantial look - the kind that reads as real painted wood from any distance, without any of the painting.

The 5-1/2-inch sleeve is only available in Classic White, and the 39-inch height is the right choice for 36-inch tall railing installed at deck surface level. If you don't have existing wood posts, Trex Structural Posts work as the interior support.

Two posts are required per railing section. Each sleeve includes a free corrugated Trex Express Railing assembly tool to help attach the railing to the post.

  • Slides over standard 4x4 pressure-treated post or post mount
  • Outside dimensions: 5-1/2 in. x 5-1/2 in.
  • Compatible with all Trex Deck Railing lines (Transcend, Select, Enhance, Signature)
  • Composite construction: won't rot, warp, split, or splinter
  • No painting or staining - ever
  • Classic White finish that mimics painted wood
  • Includes Trex Express Railing assembly tool
  • Available in Classic White only
