Everything You Need to Know About Cord Grips

Cord Grips vs. Cable Glands

Cord grips and cable glands are different names for the same thing, with cord grip being more commonly used within the United States. Depending on the region you are located in, they may be known as cable glands, connectors, strain relief, or fittings. Here at LAPP Tannehill, we tend to use 'cord grip' and 'cable gland' interchangeably.

What Are Cord Grips Made Of?

Most cord grips are made up of three components: two “halves” and a grommet.

1. The front half of the cable gland secures the gland itself, often called a cap nut or dome cap.
2. The middle section (grommet) seals and locks the cable into place so it can’t be pulled or tugged loose.
3. The final half holds the entire gland together, often called the thread.

To withstand a variety of environments, cord grips are available in a variety of metals and plastics. The right choice depends on your application. Some of the most common materials include:

There are also different choices you can make when it comes to joining a cord grip and cable together. For instance, many cord grips slide over the cable and tighten onto the jacket. Some are permanently molded to the cable. Snap-on cord grips are also available.

Why Use Cord Grips?

An essential component of cable management, cord grips ensure that your cables stay neat and orderly for easier maintenance and service. But they also provide many other benefits that support constant uptime and reduce the likelihood of cable damage or disconnection.

Where are Cord Grips Used?

Cord grips can connect all types of electrical power, control, instrumentation, data, and telecommunications cables to devices and power supplies. You’ll often find them used in aerospace applications, cleanroom environments, utilities, industrial settings (such as automotive or food and beverage manufacturing plants), and marine and railway applications.

In hazardous or harsh environments, cord grips may also be called upon to prevent flammable gas (or other potentially flammable substances) from entering equipment enclosures.

How Can You Select the Right Cable Gland?

To make sure you choose a cord grip that will work for your specific application, ask yourself these questions:

1. What type of cable will the cord grip connect to? Consider cable diameter, type, voltage rating, etc.
2. Where will the cable be located? Indoors or outdoors? In a potentially hazardous/explosive environment? Will temperatures fluctuate or stay the same?
3. Are liquids present?
4. Will consequences be severe if these cables become disconnected?

Your answers will help determine the size and type of cord grip you choose – as well as the type of gland mounting you need: adhesive, threaded or nut mount, welded, etc.

Everything you Need to Know about Cable Grips

If you don’t work in construction, or aren’t an expert, it can be hard to know what certain tools are, what they do, and how they work.

That’s why The Ratchet Shop’s website is full of handy blogs and how-to videos to make sure that all our customers know how to use our tools safely and effectively.

In today’s blog, we’ll give you the lowdown on a highly underrated piece of kit: the cable grip. Read on to see our answers to your FAQs about cable grips.

What is a cable grip?

Cable grips are a type of lifting equipment that help, as the name suggests, grip cables. This portable lifting equipment is inexpensive to maintain and can be repaired easily in the field, so it’s a popular item in toolboxes.

What is a cable grip used for?

Cable grips are an excellent lifting equipment tool used for gripping and pulling. They are extremely useful in the tensioning of messenger wire ropes, metal rods and cables.

Cable grips are also a lot more common than people initially realise. If you’ve ever travelled in an air lift or gondola, you’ll know they work by attaching themselves along a long line of cable and travelling down it. To ensure they are securely and safely attached to the cable, cable grips are used to hold them in place, as well as guide the lift along the wire.

You’ll also find cable grips used in various construction and industrial sectors, particularly those that need to be able to lift heavy loads, from 500kg all the way up to those weighing kg.

Cable grips can also be used to support electric or structural cables for pulling, as well as when the job at hand requires the laying of electrical and structural cables - who knew one little grip could be used for so much!

What is a cable grip made from?

Cable grips need to be made from a strong material to help ensure they can take the heavy loads required from them. The vast majority are made from iron to help ensure this. Being both ductile and malleable, iron cable grips are suitable to manage both the strain and continuous movement often involved with the use of cable grips.

How does a cable grip work?

Cable grips contain strong parallel jaws that are able to clamp down firmly on the wire without slippage, fraying or other types of damage - reassuring when their primary purpose is to hold up cable cars and lifts!

Thanks to the cable grip’s guide, the grip is securely attached to the wire - and remains so throughout its entire journey up and down the wire.
