Trex Railing Accessories
Trex railing accessories, including post sleeves, caps and skirts, mounting hardware and touch-up pens, built to work with every Trex railing line on decks and porches.
About Railing Accessories
Trex railing accessories are designed for universal compatibility across Trex railing lines, so the same post sleeves, caps and skirts can finish a Select, Transcend or Signature project. Colors include Classic White, Charcoal Black, Vintage Lantern and Rope Swing, along with the Transcend railing colors.
The 4 inch post sleeve fits over a 4×4 pressure-treated post, turning a framing post into a finished railing post. A 6 inch post sleeve is available in Classic White only. Flat post sleeve caps and skirts come 12 per box, which makes it easy to order by the box for larger decks. Mounting hardware and touch-up pens are also available for finishing cuts and covering scuffs after the rail is up.
For an itemized quote, tell us which Trex railing line and color you are matching, the number of posts and their size, and how many caps and skirts you need. If you are not sure how many posts your layout requires, send the deck dimensions and stair count and we can help work it out.
