Product Overview

If you’re building a railing with Deckorators® ALX Classic or Estate rail kits, you’ll need posts. This post matches those kits. You install the post on top of your decking. It comes with the base already welded to the bottom. Kit includes a leveling plate to ensure a plumb installation.

You’ll also get an aluminum skirt to cover up the base and an aluminum post cap to cover the top. The result? A beautifully cohesive railing on your deck or porch!

Like all the ALX products, this post is heavy-gauge aluminum, thickly powder-coated for a uniform, durable, hard finish that weathers outdoor exposure beautifully.

Installation: Post is installed on the deck surface, but fasteners need to be driven into the wood substructure (joists or blocking), at least 3 inches of solid wood—not including the deck board. Follow manufacturer’s complete instructions.
