Everything You Need To Know About Carbine Hooks

Whether you’re the owner of an industrial rope work company or you just like to rock climb in your spare time, the chances are, you’re going to need carbine hooks. These simple rope fittings are a quick and easy way to connect different components, offering reliable support and ensuring your safety. But the question is, do you know which type of carbine hook is best for your needs?

In the following blog, we cover everything that you should know about carbine hooks – answering your most commonly asked questions and helping you to select the best carabiner for the job.

What is a carbine hook?

Carbine hooks, also known as carabiners, are a small loop of metal with a spring-loaded section on one side. This section can be opened and closed as many times as you wish and it allows rope (and other components) to be connected in a secure yet completely reversible manner.

Typically made from aluminium or steel, they have four basic components, including a gate, spine, nose and basket. The gate is the section which opens and closes, whilst the spine is the longest side of the hook (which sits opposite). The nose is the part to which the gate snaps shut and the basket is the distinct bend in the carabiner – where the rope will naturally sit when clipped into place.

What types of carabiner are available?

They are several different types of carbine hook to choose from and these vary on four main factors:

  1. Locking Mechanism

Both non-locking and locking carbine hooks are available. Whilst non-locking hooks simply spring open and closed, when shut, the gate of a locking hook is secured in place. This either happens automatically or due to the tightening of a screw. Locking carabiners are usually heavier than non-locking varieties; however, in most cases, they are essential for health and safety reasons.

  1. Size

Carabiners come in a variety of different sizes and they are generally categorised as being ‘full-size’ or ‘mini’. The size that you need will depend on the intended application. Smaller carbine hooks are lighter and take up less space. However, they have a limited number of uses. In most situations, a larger (and heavier) hook will be the more practical and convenient option.

  1. Shape

Although many different shapes are available, offset D and pear-shaped are the most common. These share a number of common traits. For example, they demonstrate a high strength-to-weight ratio, they have a large gate for easy clipping and they hold rope securely in place. However, thanks to their round basket, pear-shaped carabiners distribute weight more evenly and reduce rope wear. Once again, the right hook shape for you will depend on its intended application.

  1. Safe working load

Carbine hooks also differ greatly in terms of their safe working load (SWL) – that is, the level of weight they are capable of holding. Before investing in a new hook, it is therefore important to note its SWL. You need to make sure it is strong enough to cope with the weight of its intended use.
