Start by multiplying the total railing length by the number of horizontal cables you plan to use. For example, a 50-foot run with 11 cables needs about 550 feet of wire. Add 10% extra to allow for trimming and tensioning. Double-check the manufacturer’s specs and your local code before cutting—both can affect spacing and final length.

Cable railings require regular cleaning with mild soap and water to remove salt, pollen, and grime that can trigger corrosion. Plan on wiping the cables every few months and inspecting the tension once or twice a year. If you have wood posts or handrails, add periodic sanding and sealing to keep moisture out. Staying on top of these quick tasks keeps the system safe, taut, and looking sharp for years to come.

Installers use high-tension fittings and precise spacing to lock each cable in place. Stainless steel strands are pre-stretched and then tightened with calibrated hardware until they meet the code-required tension. The result is a rigid infill that resists sag even under daily use. Periodic checks with a tension gauge ensure everything is dialed in, keeping the railing straight and safe year after year.

With routine upkeep, stainless steel cable railings easily last several decades. The metal resists rust, and quality fittings stay tight with minimal adjustment. Keep the cables clean and protect any wood components with fresh sealant as needed. Follow those basic steps, and you’ll likely replace the deck before you replace the railing.

Most jurisdictions set rules for maximum cable spacing, overall railing height, and minimum tension. These standards keep small children from slipping through and prevent the wires from sagging over time. Code details change by state, county, and sometimes city, so call the local building department before you order materials. Your installer should also pull the proper permits and schedule any required inspections.
