WHY KEUKA

  • No Special Tools

    The Keuka fitting installs by hand. No crimpers, no swagers, and no special equipment required.

  • Black Cable Bundle - 1/8" - Keuka Cable

    Unmatched Adjustability

    Use a tensioner fitting on both ends of your cable run for a clean, symmetrical appearance and double the tensioning capability. This ensures you never run out of adjustment and can easily re-tighten your cables years from now.

The Keuka Installation Guide

Learn how to set up your cable railing system in minutes. Watch the video below for a complete, easy-to-follow overview.

Step-by-Step Installation

Need a quick reference? Follow along with our written instructions to guide you through each phase of your build.

1. Prepare the Cable

Ensure your 1/8" stainless steel cable is cut cleanly. Slide the Threaded Stud onto the cable first. Important: Ensure the smaller end of the hole goes onto the cable first, with the larger opening facing the cut end of the cable.

2. Install the Jaws

Push the Jaws onto the end of the cable using your fingers. Slide them on just enough so that approximately 1/8" of cable is exposed at the very end of the jaws.

3. Lock the Assembly

Pull the Threaded Stud back up toward the Jaws. Pull it firmly until you feel or hear a distinct "click." This indicates the jaws are seated correctly inside the stud.

4. Install the Washer

Place the Delrin Plastic Washer onto the threaded stud assembly.

5. Connect the Fitting Assembly

Insert the Level Fitting Body into the post to meet the cable assembly. Begin threading the stud/jaw assembly into the fitting body by hand until it is hand-tight.

6. Tighten and Tension

Once all cables are installed, use your Allen wrench (or ratchet with 3/16” hex bit) to apply final tension.

Tip: Hold the cable steady with your pliers to prevent it from spinning while you turn the fitting.

Tensioning Order

To ensure equal pressure on your posts:

  • Start tightening the middle cables first.
  • Work your way out, alternating up and down (one cable above the middle, one cable below, etc.).
  • Repeat until the entire system is rigid and secure.

FAQs

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.
