1. How strong should Cable Railing be?

The International Residential Code (2) requires top rails to be capable of sustaining a concentrated load of 200 lb horizontally or vertically at any point of the railing component. Local building codes may also call for smaller loads at 20 lb per square foot applied to the cable infill.

The presence of cables is what makes cable guardrail systems unique. The posts should be sturdy enough to sustain the pulling force associated with the steel cables. Additionally, top rails are frequently exposed to light impacts and pressure from objects or individuals leaning on the structure.

2. How high should Cable Railing Posts be?

Most state residential codes require railing to be 36" minimum height. California (7) is an exception to this standard, requiring railing to be at least 42" for all residential railing installations. The 42" railing height requirement is also applicable to commercial building codes. The post height is measured from the floor to the top of the handrail.

All railing installations must comply with applicable standards related to post height and cable spacing. When determining the height of the railing posts, you should factor in the handrail, type of location, as well as local, city, and international building codes (3).

3. How far apart can Cable Railing Posts be?

A 4 ft maximum distance center to center between the posts is recommended to meet the 36" or 42" posts requirements and address the cable deflection. No opening should be larger than 4 inches. Spacing between posts should be kept consistent (when possible) along the cable assembly to assist aesthetics. Building Code (3) requires that the spacing of posts not exceed an amount that could increase the cable deflection.

4. How far apart should Cables be?

Less than 3 1/4" spacing between cables taking into account the cable deflection related to post spacing. According to the International Code Council (4), a 4" sphere should not be able to pass through gaps.

How far apart should Cables be

5. How many Cables?

Cable Railing Systems with 36" high posts should use 10 horizontal cable runs. Cable Railing Systems with 42" high posts should use 12 horizontal cable runs. Building codes dictate that no opening shall be more than 4". The 10 and 12 cable count makes the distance between the cables 3 1/8".

6. What Cable is best for Cable Railing?

1x19 Strand Stainless Steel Wire has the smoothest construction while being strong with low flex and stretch properties. These specifications (8) make it the ideal solution for railing applications.

7. Are there different types of Top Rails?

The top rail completes the railing frame required for your Cable Railing project. Stainless steel is highly recommended for the top rails. The metal is resistant to corrosion, moisture, debris, and light impacts.

Marine-grade stainless steel is applicable to railing installed in rugged locations, such as outdoor beachfront properties, docks, outdoor decks, rooftops, etc. In addition, stainless steel top rails are suitable for indoor spaces, including commercial sites, offices, and public buildings.

Some project requirements may call for wooden top rails. To ensure long-term structural integrity, individuals should consider mounting a steel bar under the wood top rail for additional support. This implementation can help keep the wood component functional and intact, mainly as safety barriers on decks, stairs, and ramps.

8. How big to Drill Holes for Cable Railing?

Intermediate posts need to be drilled to get the cable through. Drill holes about 5/64" (or 2mm) bigger than the diameter of the used cable to avoid excessive cable deflection.

9. How Long to run Cable Railing?

The recommended cable run maximum distance is 30 feet on straight runs when using a 1/8" diameter of 1 x 19 Construction Type 316 Stainless Steel Cables. A cable run consists of a cable tensioner, a cable terminal, and a wire. The rule of thumb is that on corners, cable runs end.

10. Do Cable Railing Rust?

Cable Railing made of Stainless Steel Grade AISI 316 do not rust when properly maintained especially in environments conducive to corrosion.

11. Is Cable Railing Safe?

Cable Railing is structurally safe and meets building code when properly installed. The Cable Railing structure relies on the tightness of the cable infills. End posts and corner posts need to be strong enough to support the pulling force of the cables.

Any opening shall not exceed 4". Though cable deflects; therefore, opening between cables should be less than 3 1/4" depending on the spacing between the cables.

12. How to tension Cable Railing?

Each cable run is made from one tensioner, one terminal, and a cable. Apply a tension meter tool on the cable, then twist the tensioner hardware enough to have your desired reading on the tension meter. Repeat this process on the remaining cable runs to have equal tension on all the wires.

Pro Tips IconPro Tips:

  • Start tensioning from the middle cable and then work your way out to the top and bottom. Tension the cables equally using a tension meter.
  • Avoid over tensioning the cables. See tip sheet on how to use the tension meter.
  • Cut all the wires of the same run to the same length. Make sure that all the posts are leveled from all the sides.
  • Make sure your handrail or top rail is installed properly before installing the cables.

13. How to install Cable Railing?

To install Cable Railing Systems, you mount the posts or balusters with 4' maximum apart. Then mount the top rail tubing to support the posts from the pulling force of the cables.

Run the cables from End posts through Middle posts to End Posts. No opening shall be more than 3 1/4". Tension the cables equally. Use Cable Cutters to cut any wire excess.

14. What are the Pros and Cons of Cable Railing Systems?

When deciding whether to choose a Cable Railing Systems or not, you have to weigh the pros and cons and consider all important factors. Cable Railing for decks and porches is a common choice for homeowners. Whether Stainless Steel Cable Railing Systems are an ideal deck accessory comes down to your personal preference. It's about price, aesthetics, and maintenance performance.

16. What is the Cost of Cable Railing vs. Glass Railing?

Glass railing is also popular among high-end homes. When it comes to visibility, these two are toe-to-toe — slim cables almost vanish from a distance, and panels of glass offer great visibility if they're treated to be glare-free. However, in terms of Cable Railing vs. Glass Railing costs, it isn't so close.

Cable handrails are often less expensive than glass, especially if you're using wooden posts. This is also true for maintenance — stainless steel railing systems prices drop quite a bit when you realize they don't need to be regularly wiped with a cleanser.

17. What is the Cost of Stainless Steel Cable Railing vs. Aluminum?

While prices vary between manufacturers, there's a clear winner in terms of Cable Railing made of Stainless Steel vs. Aluminum costs. Aluminum may be less durable, especially in saltwater environments, and require more maintenance, but it's less expensive than cable handrails. However, if you need a stronger and longer-lasting railing solution, Stainless Steel Cable Railing is a great investment.

22. Why Knowing Your Project Requirements is Important?

For large or complex projects, the installed Cable Railing system often includes handrails. It is recommended to double-check field measurements, dimensions, and finalized shop drawings to prevent bottlenecks. This crucial step can prevent delays and miscalculations during fabrication. If it is not possible to make field measurements, individuals may obtain guaranteed dimensions from their contractors.

Obtain guaranteed dimensions in writing by the Contractor—coordinate fabrication and delivery schedule of handrails with construction progress and sequence to avoid delay of railing installation.

23. Benefits of Professional Installation

Some people may prefer a professional installer for their Cable Railing Systems for that extra peace of mind. As railing is for Safety, Donnie Balvin from Inline Design explains that "It's advisable to get a professional because of this factor." Donnie also notes that "Handy DIY customers can install most of our products. But to install an entire system like our Arcadia, a welder is required since the top rail needs to be cut/mitered and welded on the job site."

Cable Railing is a practical and stylish way to make a home or business space safer.
