In order to install the cable railing in the correct way, the posts need to be secured at the proper spacing by running the cable from the end post through the mid post to the end post. Then, please tension the cable to minimize the deflection as much as possible. Repeat these steps for each stainless steel cable. According to building and cable railing code standards, 4″ spheres aren’t allowed to pass between cables. Therefore, we recommend cable spacing of no more than 3 inches. To ensure adequate strength and control of cable deflection, we recommend using one post every 4 feet.
