Showing 0:29–0:46 of the source video.
After the cables are threaded, proceed to tension them. Use locking pliers to firmly grasp the cable near the tensioner to prevent it from slipping. Then, use an adjustable wrench to turn the tensioning nut on the hardware, slowly tightening the cable until it is taut. In the video, a small piece of wood is placed between the locking pliers and the post to protect the wood from damage during the tensioning process. Repeat for each cable until the desired tension is achieved. Ensure all cables are evenly tensioned to maintain a uniform look and structural integrity.
Goal: Achieve appropriate tension on all installed cables
This project guides through the installation of a cable railing system on a wooden deck. It involves securing specialized hardware to wooden posts, meticulously threading stainless steel cables through these fittings, applying appropriate tension to each cable to ensure a secure and taut barrier, and finally trimming any excess cable for a professional and clean finish. The process enhances the deck's aesthetic with a modern, open feel while providing a safe perimeter.
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.
This project outlines the steps to install a cable railing system on an existing staircase, enhancing safety and aesthetics. It involves measuring, cutting, drilling, and assembling the railing components, including posts, cables, and tensioners.
