Cable Railing Kit Considerations

Cable railing kit tips and safety considerations. Considerations when selecting a cable railing system that will meet your application and aesthetic needs.

Cable railings are great for installation on stairways, decks, and balconies where you do not want your perfect view to be blocked. Instead of bulky pickets or spindles, cable railings are see-through, ultra-thin barriers. Made of stainless steel in many styles, they are very strong and can withstand the elements.

Cable railing kits are designed to provide a clear view profile, which means that you are dealing with smaller and narrower components.

Safety and code considerations for a cable railing kit

The Ladder Effect

The ladder effect can be a safety issue. It is unique to railing infills that run horizontal, and it is based on the concept that when you are offered something that looks like a ladder, people will try to climb it like a ladder. This can pose a danger if you do not follow the manufacturer’s instructions.

4” Sphere Rule

This code rule says that no balustrade (infill) can be spaced more than 4″ apart. This rule applies to all railing systems, but it becomes a bit more complex when it comes to cable railing because cables have a slight deflection factor when pressed or pulled in any direction. Cable railings inherent deflection means that cable spacing must be much closer together than 4 inches or it will not pass the 4″ sphere test. The cable’s tension should be powerful enough to prevent the cables from moving when the pressure from the sphere is exerted.

We recommend 3 ” spacing at a maximum of 4-foot post spacing. If a post is farther apart then 4 foot the cable must be moved closer.


In case your deck has a stairway, you must have a graspable and continuous handrail. If your stair rail profile is greater than a basic 2 x 4 you might need to add a handrail to the cable railing kit. 

To fully comprehend the graspability requirements, you should understand the disparity between guardrails and handrails. A handrail is designed to provide you with something to grab when walking along the stairway. Conversely, a guardrail is made to prevent you from falling over the edge.
