When it comes to achieving accurate and reliable control in your application, correct adjustment of your vernier control head is essential. While every vernier cable is factory tested prior to dispatch to ensure smooth and correct operation, real-world installations often require fine-tuning to suit specific conditions.

This guide walks you through the simple steps to adjust your vernier head in the field—helping you get the exact performance and feel your application demands.

Understanding the Key Components

Before making adjustments, it’s important to familiarise yourself with the main parts of the vernier head:

• Release Button

• Throttle Adjustment Knob

• Vernier Shaft

• Brake Adjustment Wheel

• Brake

Each component plays a role in delivering both coarse and fine control, as well as the overall feel of operation.

Step-by-Step Adjustment Guide

1. Macro Adjustment (Large Movement)

To make larger positioning adjustments:

• Depress the Release Button

• Move the control to the desired position along the Vernier Shaft

This allows for quick, broad movement when setting your initial position.

2. Micro Adjustment (Fine Tuning)

Once your general position is set, fine-tune with precision:

• Turn the Throttle Adjustment Knob clockwise or counterclockwise

• This provides small, controlled adjustments for accurate positioning

This is ideal for applications where precision control is critical.

3. Adjusting Operating Feel

To customise the resistance or “feel” of the cable:

• Turn the Brake Adjustment Wheel clockwise to increase friction

• Turn it counterclockwise to decrease friction

This adjustment changes how heavy or light the control feels during operation, allowing you to match operator preference or application requirements.

Why Field Adjustment Matters

No two installations are exactly the same. Factors such as mounting position, load requirements, and user preference all influence how a control cable should perform.

Taking a few minutes to properly adjust your vernier head ensures:

• Improved control accuracy

• Better operator comfort

• Increased system efficiency

• Reduced wear over time

At Industrial and Cable Group we are often approached about replacement of control cables and how to accurately measure it and or find something that will fit a specific application.  

The first thing to check for is a part number – some cables have it heat stamped on the outer / conduit of the cable.   It may have also have a brand name printed on it, for example - Morse or Teleflex.  If you know this then we can more than likely can help you with finding a replacement.

If you can’t find this then the answer is to look at the cable you’re replacing; measure it from tip to tip, then take note of what type of cable ends it has eg Bulkhead or Clamp (threaded or grooved).  Most cable types are measured tip to tip but there are some exceptions to this rule.

The other pieces of information you will need is an understanding of the Cable Series you’re replacing that corresponds to the size of the rods it has.  For example, 30 Series has 3/16” Rod, 40 Series – 1/4” Rod and 60 Series – 5/16” Rod.  Our 40 Series can also come with metric rods at 6mm and 60 Series with metric 8mm rods.  Other control cables may have differing identifying factors.

The next step is knowing what length of travel you need – our standard options offer between 25mm through to 150mm.

In summary the pieces of information you need are:

• What Ends?
• What Travel?
• What Length?
• Does it have a part number or brand?

Of course, it you can’t find what you’re looking for on our site then we suggest taking photos of your old cable and sending them to us so we can offer some assistance.  Use our CONTACT US FORM or email to sales@industrialandcable.com.au
