Product Overview

This Cable Rail Line Post Kit is part of the beautiful Deckorators® ALX Contemporary Cable Railing system. This smart system eliminates time-consuming, complicated steps like drilling perfectly aligned holes and fussing with turnbuckles.

The Line Post (aka horizontal post) is installed between End or Corner Posts in a run of railing where cables will be run in a straight line. The post is already drilled on 2 sides for cables—that saves you a headache right there. And, the hardware that tightens and secures the cables is hidden in the post.

Kit includes a leveling plate and predrilled aluminum base that you attach to the deck. Fasteners must go through the decking into a floor joist or proper structural blocking. Post fasteners are not included.

The post is heavy-gauge aluminum, thickly powder-coated for a uniform, durable, hard finish that weathers outdoor exposure beautifully. Complete your post installation with the included matching post base trim and post cap. You can replace the included post cap with a lighted post cap, available separately.

To complete your cable railing, you will also need Cable Kits, a Top Rail Kit, End Posts, and Corner Posts (depending on your deck layout). The 36-inch posts have 10 holes, so you’ll need 10 Cable Kits. The 42-inch posts have 12 holes, so you’ll need 12 Cable Kits.

TIP: To reduce rust deposits on the stainless steel cable, use clean tools. Don’t install cable railing with rusty tools, because they can leave rust deposits on the surface of stainless steel fittings..
