Install and Tension Cable Strands

What happens in this clip

Measure the distance between the posts for each cable run. Using specialized cable cutters, cut the stainless steel cable strands to the required lengths, adding extra for the tensioning hardware. Thread one end of a cable through the pre-drilled holes in the posts and install the appropriate tensioning hardware (e.g., a fixed end fitting with a washer and nut). Then, thread the other end of the cable through the remaining holes and attach the tensioning mechanism (e.g., a turnbuckle or a tension receiver). Gradually tighten the tensioning hardware using a wrench or a specialized tensioning tool until each cable is taut and firm, ensuring proper sag minimalization while adhering to local building codes for cable spacing and tension.

About the full video

This video demonstrates the step-by-step process of upgrading existing flimsy stair railings to a modern, durable cable railing system from Muzata. The project covers removing old railings, meticulously marking and installing new posts onto a concrete surface, attaching handrail sections, and finally, installing and tensioning the cable strands to create a sleek and visually open railing.

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.
