Key Features

  • Easy installation: slides directly over your existing 4x4 wood post or structural post insert
  • Durable, weather-resistant composite material extends the life of your railing
  • Classic look of wood railing - without the demanding wood maintenance
  • Never needs to be painted, stained, or sanded

Color Options

Charcoal Black, Classic White, Gravel Path, Rope Swing, Tree House, Vintage Lantern

Note: the 5-1/2-inch post sleeve is only offered in Classic White.

If you don't have existing wood posts, use Trex Structural Posts inside your post sleeves.

How To Choose Your Size

Both post sleeves only fit over nominal 4x4 wood posts or structural posts.

Choose the 4-1/2-inch sleeves for less visual obstruction. Choose the 5-1/2-inch posts for a more traditional, substantial look, or to more easily connect rails at unorthodox angles.

How To Choose Your Height

For 36-inch tall railing:
  • Choose 39-inch post sleeves for the surface of your deck
  • Choose 54-inch post sleeves for the middle and bottom of your stairs

For 42-inch tall railing:
  • Choose 54-inch post sleeves for all posts
