11 FAQs About Cable Railing

Here’s a rewritten version of your content in English: --- It’s essential to get the details right when installing a cable railing system. Let’s dive into some common questions and considerations to ensure your project meets safety standards and looks great. First off, how far apart should your cables be? According to the National Building Code, cables should ideally be spaced no more than every 3 inches. However, many U.S. counties follow a standard of 4-inch spacing. Always double-check with your local building inspection office to avoid any surprises. Next, let’s talk about post spacing. The National Building Code suggests keeping posts no more than 6 feet apart. This ensures a sturdy installation. Keep in mind, though, that closer post spacing will make your railing even more rigid and secure. If you want optimal performance, stick to the 6-foot maximum. Now, how long can your cable spans be? For straight runs or those with a single angle change, we recommend keeping spans under 75 feet when using a single set of tensioning fittings. For longer runs, consider consulting with a professional to explore specialized solutions. Speaking of tensioning, how tight should your cables be? National Building Code mandates that cables be spaced closely enough so that a 4-inch sphere can’t fit through. While this might be challenging to measure, aim for a tension level that feels solid yet manageable—enough to meet local codes. When it comes to handrail height, the National Building Code allows a range between 36 and 42 inches. Always confirm these requirements with your local inspectors to stay compliant. Do you need cable cutters to cut your cables? Absolutely! Using alternative tools like bolt cutters or angle grinders can damage the cable ends and make it tough to insert them into fittings. Cable cutters are specifically designed to provide clean cuts, saving you time and hassle. What about swaging tools? Not all tools work with cable railing systems. Regular rigging swagers may deform the fittings, leading to weak connections. For HAAS REVO and AXIS Systems, use the Crenshaw Cable Railing Swage Tool or another recommended swager to ensure a strong, reliable connection. Are post protectors necessary? While they’re optional, post protectors enhance both the look and functionality of your railing. They help prevent wear and tear while adding a polished finish. Learn more about their benefits here. Choosing the right cable is crucial. We recommend 1X19 Type 316 stainless steel cable in 1/8” or 3/16” diameters. This material is highly corrosion-resistant, rigid, and minimizes stretch, making it perfect for outdoor use. Deciding between 1/8” and 3/16” cables depends on your preference. 1/8” cables are lighter and easier to handle, offering a sleek appearance. On the other hand, 3/16” cables provide added strength and security due to their thicker diameter. Finally, will your cables sag over time? In most cases, especially with metal or hardwood posts, sagging is rare unless the system sustains damage. However, pressure-treated lumber decks may experience slight tension loss, which is easily fixed during routine maintenance.
