Technically regardless of the span between your posts and the spacing between your cables it is still going to be possible with enough force to spread the cables to 4 and beyond. In a cable railing system horizontal cables are used across guard rails and handrails to provide safety in place of traditional spindles glass mesh etc. They must be securely mounted to ensure they wont bend when the pressure of over 200 lbs is applied by the high-tension of cables.
Calculating the space between the railing posts is the first step in the railing installation process. What is the spacing for cable railing. Cable Railing Post Spacing.
The other important component of cable railing installation is the spacing between posts. The top rail. Post Heights and Cable Spacing.
The stabilizer bar is mounted with simple brackets and will minimize cable deflection. Cable spacing is also important for the minimization of cable deflection. Decide how many cables runs your fence needs and purchase enough cable to enclose your perimeter.

If you wish to maintain3 spacing for cable sections that span over 5 feet we offer a Cable Stabilizer Kit made from 1 stainless steel tubing.
Our standard cable spacing is 3 on-center running the length of each post. The other important component of cable railing installation is the spacing between posts. View in gallery The end fittings are the elements that connect the whole railing system.

Slender spacers may be used instead of some of the larger intermediate posts to achieve a more open railing design. Buy enough cable to enclose the area. For child safety the balusters or other decorative infill must be spaced less than 4 inches apart a 4-inch-diameter ball should not pass between the balusters.
3 oc cables would have 12 max deflection. Use materials such as 2 x 2. Factors influencing this rigidity are.
If you wish to maintain 3 spacing for cable sections that span over 4 feet max. They must be securely mounted to ensure they wont bend when the pressure of over 200 lbs is applied by the high-tension of cables. That is why we recommend 119 construction type 316 stainless steel strand.
Begin by measuring the distance between the corner posts of the deck making.
