Installing a Synthetic Railing System

Project Overview

Almost every manufacturer of synthetic decking materials makes a corresponding synthetic railing system-some in more than one style. The components consist of the pieces normally associated with railings-all the parts needed to complete your deck in a consistent style. Some come with railing posts, others with a sleeve that is made to slip over the post so its appearance matches that of the rest of the system.

Step 1

INSTALL POSTS

Install pressure-treated railing posts or synthetic posts if supplied by the manufacturer, spacing the posts according to the manufacture’s instructions. Slide the post skirts over the posts and let them rest on the deck. Insert two railing brackets into the assembly tool and push the tool on the interior faces of the post sleeves. Attach the brackets to the posts with the screws provided. Remove the tool and repeat the procedure on every post. If your railing does not come with any assembly tool, attach the brackets at the positions specified by the manufacturer.

Step 2

INSTALL BALUSTERS

Lay the assembly tool face up and place balusters in the slots. Insert all balusters into the channel on the top rail, making sure that the distance from the end of the top rail and the first baluster are equal on both ends. Fasten the balusters with predrilled screws through the bottom lip of the top rail. Move the spacing tool to the bottom of the balusters and slide the bottom rail against them, with the end spacing equal to that of the top rail. Fasten the balusters to the bottom rail by driving predrilled screws through the underside of the rail.

Step 3

CUT SUPPORT BLOCKS

Cut support blocks to the manufacturer’s specification from the balusters with a power mitersaw. Fasten the support blocks with predrilled screws driven through the lip of the bottom rail. Take the complete railing section and place it between the posts, keeping it raised slightly above the mounting brackets.

Step 4

ATTACH RAIL TO BRACKETS

Let the railing section down on the brackets. Fasten it to the top rail by driving a screw through the holes in the mounting bracket into the railing. Fasten the bottom rail by driving a screw through the top of the rail into the bracket. Repeat the process for the remaining sections. Finish the railing by attaching the post caps according to the manufacturer’s instructions. Some are made to snap into the post skirt, others require the application of construction adhesive.
