Product Overview

Installing a stair railing with Deckorators® ALX Classic or Estate stair railing kits? You’ll need posts!

This post is compatible and comes in matching colors. The post 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 stair railing on your deck or porch!

Like all the ALX products, this stair 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 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.
