Final Cable Tensioning

What happens in this clip

With all cables installed and hand-tightened, proceed to the final tensioning. Work from the center cables outwards to ensure even tension across the entire railing. Use a wrench or the manufacturer's specialized tensioning tool to tighten the adjustable hardware. Apply sufficient tension to make the cables taut, but be careful not to overtighten, which could damage the posts or hardware. Periodically check the tension and adjust as needed until all cables are uniformly tight and meet safety standards.

Goal: Achieve proper tension across all cables for safety and aesthetics.

This project provides a concise overview of installing cable railing on stairs. It covers essential layout considerations, including code-compliant spacing, proper hardware installation techniques, cable cutting and seating, and the final tensioning process to achieve a secure and aesthetically pleasing railing system.

Step 9 of 11: Install Tensioners and Tension Cables

On the final post of each run, install a tensioning device (e.g., a turnbuckle or a threaded terminal with a nut). Thread the cable end through the tensioner and secure it, often by swaging or using a specialized fitting. Gradually tighten the tensioners to remove slack from the cable. Aim for a taut cable that produces a clear 'ring' when tapped, but avoid over-tensioning, which can damage posts or hardware. Check tension regularly during the process.
