Classic Cable vs. Single Tensioner
Traditional cable railing systems utilize a single tensioner at each cable location typically at one or both ends of the railing frame. Single tensioner cable railing systems feature a single cable running through all of the railing posts and tensioned from a single point inside an end post. The main premise to the single tensioner system is to minimize hardware, tools, and simplify installation. Most of these types of systems are utilized for level deck railings and can be found at big box retail outfits.
Installation Process Similarities and Differences
Standard cable railing systems are installed a cable at a time; each cable having it’s own fitting. Single tensioner cable railings are threaded through all the posts and anchored on one end; then tensioned from a single point. The single tensioner system contains less parts due to its design which is where it shines and could also save time in certain situations. Additionally, minimal tooling is needed. The drawbacks however can be substantial and very unforgiving when these systems are misaligned causing difficulty tensioning the entire system. Complex layouts can greatly affect cable routing and successful tensioning and installation can require more skill for DIY installers.
Cost Comparison-Single Tensioner vs. Traditional Cable Railing Systems
Lower material costs are on every remodelers mind and railing costs for high quality systems can be high in comparison to standard picket rails and traditional options. Single tensioner systems attempt to lower costs with less fittings and potentially lower labor costs. In some situations users will actually experience the opposite reaction; as any complex set up is problematic. The lower labor cost scenario will rarely apply outside of a simple straight run of cable. The single tensioner set up will of course be less expensive for shorter linear designs. Classic cable railing with individual tensioners will require more fittings and possibly more labor; however installation is much more straightforward and versatility abounds with classic systems.
What About Maintenance Costs?
As even the lowest maintenance railings require care over time we have to think about maintenance. Imagine the implications of a single tensioner vs individual tensioner system if a repair is needed. Single tensioner systems are much less reliable and more difficult to repair or maintain; especially in tough conditions or high load dynamic environments.

Performance and Durability
Our team of professionals at SDCR consists of sales and fabrication pro’s and railing contractors.We assist our customers with cable railing design and code compliant products for the highest performance. Our preferred installers have built thousands of railings since 2006, while testing our products in some of the harshest environmental conditions. Below is a quick breakdown of performance and durability bullet points comparing the two systems:
-Tensioning- consistency is much better with individual cables, Possible trouble shooting over time and/or repair is much easier with individual cables and classic cable railings.
–Durability- Although stainless cable is very durable; a single tensioner is a potential failure point to compare vs. the benefit of convenience provided by these systems. Classic systems have been used in marine environments for decades. Single tensioner systems have not been proven yet over time.
-Aesthetics- customers interested in minimal hardware may prefer single tensioner aesthetics although many of these systems require more posts and also larger post sizes due to aluminum construction. Aside from the possible cost savings in certain situations, the classic system outperforms in most applications.
Single Tensioners and Custom Cable Railing Applications
The versatility provided by individual tensioners and classic cable systems is unmatched by single tensioner systems. Corners and sloped applications increase friction and uneven tension which negates the benefit of a single tensioner. The best use case for these systems is a single linear run which is just not a common occurrence. Curves and stairs provide additional challenges for single tensioner systems. Classic cable railings excel in custom situations with precision and security. Code compliance is also easier due to independent tension, localized adjustment and true time tested proven results.
