Install Cap Nuts and Final Tensioning

What happens here

The final step is to install the decorative cap nuts over all exposed cable fittings, both on the tensioning ends and the newly crimped and trimmed fixed ends. These cap nuts provide a finished, aesthetic look and can also help protect the cable ends. Once all cap nuts are in place, go back to the tensioning ends and use an appropriate wrench (not explicitly shown but implied for final adjustment) to apply final tension to all cables. Tighten them evenly until they are taut, firm, and parallel, ensuring your railing is secure and meets any local building codes for deflection.

Goal: Complete the railing aesthetics and ensure proper cable tension
