Thread Cables Through Railing Posts

What happens in this clip

With the through-post fittings installed, carefully feed the long length of stainless steel cable through all the consecutive posts along the railing run. Ensure the cable runs smoothly without kinks or obstructions.

Goal: Pass all cables through the installed fittings for the entire railing length.

What's used

Tools

• Stainless Steel Cable
• Aluminum cable

About the full video

This DIY project demonstrates how to install a modern cable railing system on a deck. It involves preparing deck posts by drilling holes, installing specialized through-post cable fittings, threading stainless steel cables through these fittings, securing one end of the cable with a swaged sleeve using a crimping tool, attaching the other end to a tensioning mechanism, and tightening the cables to achieve proper tautness. The process concludes with trimming excess cable and installing decorative grommets for a clean, finished appearance.

Step 8 of 11: Thread Cables Through Posts

Carefully thread the free end of each cable through the designated holes or fittings on the next posts in line. For stair railings, ensure the cable follows the angle of the stairs smoothly. Avoid kinking or damaging the cable during this process. If the cable is stiff, a cable puller tool might be helpful.
