Product Overview

If you’re building a railing with Deckorators® ALX Pro Rail Kits, you can cover the top rail with this cap rail for a more substantial appearance. Installation is easy and fasteners are hidden for a truly sleek look. Note that the Pro Rail Kit is a 2 in. x 4 in. railing, so this Cap Rail is not compatible with the ALX rail kits that use 2.5-inch posts.

How it works: Attach cap rail insert to top rail, then fit cap rail over insert. Follow manufacturer’s complete instructions. Self-drilling screws are included. You will also need exterior-grade construction adhesive.

The Cap Rail is heavy-gauge aluminum, thickly powder-coated for a uniform, durable, hard finish that weathers outdoor exposure beautifully.

Installation Instructions: can be found here.


  • Limited lifetime warranty on manufacturing & powder-coating defects
  • 25-year removal & replacement warranty
  • 10-year limited salt & coastal water limited warranty
