Why Go Swageless?
Skip the expensive tools and permanent mistakes. Discover why both DIY homeowners and professional contractors prefer Keuka's crimp-free fittings.
Traditional Crimped
-
Expensive Tools Required
Requires buying or renting a heavy, expensive hydraulic swaging tool to complete the installation.
-
Permanent Mistakes
Once you crimp, it’s permanent. If a measurement is off, you have to cut the cable and throw the fitting away.
-
Time Consuming
Pumping a hydraulic press for dozens of cable ends takes a heavy physical toll and slows down the project.
Swageless System
-
No Special Tools
Installs rapidly using pliers and an open ended wrench. No hydraulics required.
-
100% Adjustable
Cables naturally settle over time. Our fittings allow you to quickly re-tension your runs years down the road without cutting or replacing parts.
-
Engineered for Strength
Features a specialized mechanical locking jaw that securely bites into the cable, making it perfect for both DIYers and pros.

The Keuka Installation Guide
Step-by-Step Installation
1. Install the Lags
Begin by driving the Lag Screw (hanger bolt) into your wood post. Start by hand to get it snug, then finish tightening it using your 7/16” wrench until it is securely seated.(Note: Once the lag stud is installed, attach the stainless steel fitting body onto it if not already pre-assembled).
2. Assemble the Cable End
Slide the Threaded Stud onto the cable, ensuring the smaller end of the stud goes on first. Next, slide the Jaws onto the cable with your fingers, leaving approximately 1/8” of cable exposed at the very end.
3. Lock the Assembly
Pull the Threaded Stud back up over the Jaws. Pull firmly until you feel or hear a distinct "click." This indicates the jaws are locked into the stud.
4. Connect to the Fitting
Insert the cable assembly (stud and jaws) into the fitting body mounted on your wood post. Thread it in by hand until it is nice and tight. Ensure the stud is screwed at least halfway into the fitting so no threads are exposed.
5. Measure and Cut the Opposite End
Run your cable to the terminating post. Pull the cable tight to the end of the fitting and then mark it to be cut 1/2 inch short. Cut the cable at this mark and repeat the assembly process (Steps 2 & 3) for this end.
6. Tension the System
Once both ends are connected by hand:
- Use your Cable Gripping Pliers to bite down and hold the cable steady (to prevent it from spinning).
- Use the 7/16” wrench to turn the fitting body.
- Tighten until the cable is taut and snug.
How far apart do I space my cables?
Approximately 3" apart. The general rule is that a 4" ball should not pass through the railing infill. Cables are flexible therefore 3" spacing is recommended.
What is swaging?
To swage (pronounced swaj) is to press a solid fitting or threaded end onto a cable using the force of either a leverage type hand tool or hydraulic press. The tool has dies that shape the fitting to a specific diameter. Also sometimes referred to as a crimper.
What does swageless mean?
A cable fitting that is swageless does not require a swaging tool to install it on a cable. Swageless fittings generally have jaws that "bite" into the cable under tension. All the Keuka fittings are "swageless".
How far apart do I space my posts?
48" maximum distance between posts is recommended. This is also to help prevent cables from separating.
What colors do the cables and fittings come in?
Currently the cables are available in stainless and blackened stainless steel.
What is the best cable size for cable railing?
1/8" diameter is the most commonly used cable diameter. It is also relatively transparent. Larger diameter cables become more difficult to manage as the thicker cable has more spring back force and becomes more difficult to cut and bend on site.
Where are Keuka products made?
Our products are proudly made in the United States.
How tall should my railing be?
36" measured from the surface of the deck to the top of the railing for most residential applications. 42" is required for commercial applications and also for California residents on guard railing. Guard railing is defined as any railing that presents a fall hazard (30" above ground or higher).
Is cable railing safe for children?
Yes. The flexibility and small diameter of small cable makes it difficult to grasp and climb. Of course no railing is climb proof.
Can cable railings be used outside?
Yes, cable railings can be used inside or outside. Mother nature will cause any product to weather at an accelerated rate which will not be experienced indoors.
How do you ship your railing parts?
We ship all orders via FedEx.
