How to Install Cable Rail on Stairs

Moments in this video

1. 0:10–0:35 Understand Cable Rail Layout and Code From Cable Railing Installation, Step 4: Mark Cable Attachment Points

   Begin by understanding the critical code requirements for cable railing on stairs. The bottom cable must be installed low enough so that a 6-inch sphere cannot pass through the triangular space created at the riser. Additionally, the spacing between individual cable rails should not exceed 3 inches. Use a 3-inch wide board as a visual guide to ensure proper spacing and determine the correct angle for installing the cable run. The angle of the cable run dictates where the hardware will be installed on the posts. Depending on the manufacturer, the upper hardware might be installed below the center of the run, and the lower hardware above the center of the run at the base, to maintain a consistent line.

2. 0:53–1:00 Measure, Cut, and Insert Cable From Cable Railing Installation, Step 6: Cut Cables to Length

   Always install the cable at the non-adjustable end first. Thread the cable through the non-adjustable hardware until it's secure. Then, pull the cable taut along its path towards the adjustable end. Mark the appropriate length on the cable at the adjustable end using a marker, ensuring there is enough excess for the tensioning mechanism. Carefully cut the cable at the marked length using specialized wire cutters designed for cable, which will ensure a clean cut without fraying. Finally, insert the freshly cut end of the cable into the adjustable tensioning hardware.

3. 1:09–1:18 Final Cable Tensioning From Cable Railing Installation, Step 9: Install Tensioners and Tension Cables

   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.
