The 4 inch Sphere Rule is a common building code standard. It simply states that a ball with a diameter of 4 inches should not fit between lines of cable. For this reason, we recommend a cable spacing of no more than 3 ⅛ inches.
Post spacing plays a crucial role in how much the cables will deflect as well as handrail strength. For this reason, we recommend using posts every four feet.
Tools Needed To Install Cable Railing
Installation requires some basic hand tools like a power drill and driver. You will also need some specialized tools for cutting and crimping your fitting onto the cable. In addition, use special fittings to tension the cable and to give intermediate posts a finished look.
The process will be similar whether you’re installing cable railing on stairs, decks, or balconies.
