Best Stainless Steel Rail System Components for Cable Railing
A stainless steel cable rail system combines cable, fittings, and supporting posts or rails to create a streamlined railing. For a 5/32-inch Atlantis RailEasy setup, the 500-foot cable spool suits larger projects, the 100-foot spool fits smaller runs, and the tensioner kit provides matching hardware. The MR. RAIL set is a separate option for 1/8-inch cable and wood posts, so it should not be mixed with 5/32-inch components.
| Product | Best For | Size Or Package |
|---|---|---|
| Atlantis RailEasy 500-foot Cable | Large 5/32-inch cable projects | 316L stainless steel, 1×19 |
| Atlantis RailEasy Tensioner And Swivel-End Kit | Matching fittings for a RailEasy system | Ten of each fitting |
| Atlantis RailEasy 100-foot Cable | Smaller 5/32-inch cable projects | 316L stainless steel, 1×19 |
| Atlantis RailEasy Tensioners | Projects needing tensioners separately | Ten tensioners |
| MR. RAIL Hardware Set | 1/8-inch cable and wood posts | Ten pairs, fittings and screws |
Atlantis RailEasy 500-Foot Cable
This 500-foot spool is best for larger cable railing projects that use 5/32-inch cable. Its 1×19 strand construction is made from 316L marine-grade stainless steel, and the listing identifies it as compatible with Atlantis RailEasy and RailSimple 5/32-inch cable railing fittings. It was selected as the large-project option because the longer spool can serve extended runs without choosing multiple shorter spools.
Choose this if your system is designed for the specified cable diameter and you need a substantial cable supply. Limitation: the cable is not a complete railing kit; compatible fittings and other system components are needed separately.
RailEasy Tensioner And Swivel-End Kit
This set includes ten RailEasy tensioners and ten swivel ends for 5/32-inch cable railing. The tensioner is described as the primary device for tensioning and fastening cable; the swivel end serves as a fixed end fitting for surface mounting. The listing identifies straight runs and stairs as intended applications, making the package a practical choice for buyers assembling a matching RailEasy hardware set.
Best for: a project that needs both tensioning fittings and swivel-end fittings in one purchase. Limitation: the package does not list cable, posts, or a complete railing system, so verify that the remaining components match your layout.
Atlantis RailEasy 100-Foot Cable
This 100-foot spool has the same listed cable specifications as the longer RailEasy option: 5/32-inch diameter, 1×19 strand construction, and 316L marine-grade stainless steel. It is compatible with Atlantis RailEasy and RailSimple 5/32-inch fittings. It was selected for smaller projects or buyers who want a shorter cable supply rather than a 500-foot spool.
Better for: compact railing layouts using the specified Atlantis cable fittings. Limitation: the listing does not include tensioners or end fittings. Estimate cable needs for the full project before selecting a spool size.
Atlantis RailEasy 5/32-Inch Tensioners
This 10-pack of 5/32-inch RailEasy tensioners is intended for tensioning and fastening cable railings. The listed patented mechanical swage fitting allows installation and tensioning with simple hand tools. A slotted base allows angles up to 45 degrees on stair applications, according to the product details.
Best for: buyers who already have the cable and need RailEasy tensioners as a separate component. It offers a focused alternative to the kit that also includes swivel ends. Limitation: this package lists tensioners only, so it does not replace the other fittings needed to complete a railing run.
MR. RAIL 1/8-Inch Wood-Post Hardware
This set includes ten tensioners, ten end fittings, and forty 1-1/2-inch number 8 wood screws. The manufacturer describes the fittings and screws as 316 stainless steel and specifies use with 1/8-inch stainless steel cable, wood posts, straight runs, and angled stair sections. It was selected as a wood-post hardware alternative for a different cable size than the RailEasy components above.
Choose this if your design calls for 1/8-inch cable and wood-post fittings. Important limitation: it is sized for 1/8-inch cable, not the 5/32-inch Atlantis cable in this guide. Confirm the cable diameter and post requirements before combining components.
Buying Guide: How To Choose A Stainless Steel Rail System
Which cable diameter does your system require?
Start with the cable diameter specified for your railing design and fittings. The Atlantis cable and fittings listed here are for 5/32-inch cable. The MR. RAIL set is for 1/8-inch cable. These sizes are not interchangeable based on the supplied product information, so match cable, tensioners, and end fittings by diameter and system.
How much cable should you buy?
Compare the length of the planned runs with the available spool sizes. The 100-foot RailEasy spool is the smaller option, while the 500-foot spool is listed for larger projects. Account for the actual layout and installation plan; do not assume a spool length will cover a project without measuring.
Do you need cable, fittings, or both?
Cable is only one part of a railing system. Tensioners provide a way to secure and tighten cable, while end fittings serve their specific connection roles. The RailEasy kit bundles tensioners and swivel ends; the separate tensioner pack is useful when those fittings are needed without another set of swivel ends. Check the full component list against the project plan.
What should you consider for stairs or outdoor locations?
For angled stair applications, the RailEasy tensioner listing specifies a slotted base that can achieve angles up to 45 degrees. For outdoor or coastal projects, compare the listed stainless steel grades and confirm that every component suits the intended environment. The Atlantis cable is listed as 316L marine-grade stainless steel; the MR. RAIL hardware is listed as 316 stainless steel.
Frequently Asked Questions
What is included in a stainless steel cable rail system?
A cable railing typically requires cable and compatible fittings, along with the supporting posts or rail components required by the design. The products here are components, not complete systems.
Can 5/32-inch cable be used with 1/8-inch fittings?
The listed products specify different cable sizes. Use fittings specified for the cable diameter and system rather than assuming 1/8-inch and 5/32-inch components are compatible.
Is the RailEasy cable available in more than one length?
The products listed here include 100-foot and 500-foot RailEasy spools. Both are specified as 5/32-inch, 1×19 cable made from 316L marine-grade stainless steel.
Does the MR. RAIL set include cable?
The listed package includes ten tensioners, ten end fittings, and forty wood screws. Cable is not listed as included.
