Carabiner Buyer’s Guide Overview

Carabiner Shape Overview

The shape of a carabiner is an important consideration to make, as different shapes are intended for different applications. There are four carabiner shapes: Asymmetric D, standard D, Pear, and Oval.

Asymmetric D

One of the most popular and versatile types of carabiners, the asymmetric D shape is characterized by it’s offset ‘D’ design. Their shape adds to their versatility, although this particular shape isn’t quite as strong as a standard D carabiner. Asymmetric D carabiners are also known for being strong and lightweight, similar to those carabiners used to support hammocks and hammock nets.

Standard D

The original D shape carabiner remains popular for certain applications, although its popularity has waned thanks to the advent of the asymmetric D shape. These ‘biners tend to hold weight along the spine, instead of the gated side, which makes them the strongest of all carabiner shapes. However, they have a smaller gate opening which makes them less useful for certain applications, such as tying a Münter hitch.

Pear

Similar to the asymmetric D shape, a pear-shaped carabiner features a symmetrical shape similar to a pear, or the human ear. These ‘biners have very wide gate openings, which makes them very useful for belaying and rappelling. This shape is typically less strong than both D shapes, but thanks to modern manufacturing processes, there are plenty of extremely strong Pear-shaped carabiners available.

Oval

The original shape of carabiners, the oval isn’t as popular as it once was thanks to the invention of newer and more specialized shapes. However, it’s still very useful for certain applications. The symmetrical design helps to prevent load shifting. The large internal size is also great for carrying gear. However, they tend to have a small gate opening which limits their utility for certain types of climbing.

Carabiner Gates Overview

The closure of a carabiner is referred to as the gate, and there are three different configurations available: straight, bent and wire.

Straight

Straight gates are by far the most popular gate style, and you’ll find them on the majority of quality carabiners. They’re made of a straight piece of aluminum, and they’re ideal for every application.

Bent

Bent gates are less popular than straight gates, but they’re equally useful. These gates feature a concave bend in the middle, which makes it easier for you to clip your ‘biner to a rope. They’re a popular choice for the rope end of quickdraws.

Wire

Wiregate carabiners get a bit of a bum rap thanks to they’re stripped down and modest appearance. Many climbers mistake this look for being less strong than straight or bent gates. Meanwhile, most wire gate carabiners are every bit as strong and reliable as their counterparts. However, they tend to be a bit less durable. Wiregate carabiners are also usually lighter.

Keylocks

A feature you’ll come across on many popular straight and bent gate carabiners is a keylock. A keylock is a smooth notch along the top end of the carabiner, where the body meets the gate.

This smooth area helps to eliminate snagging which can damage your gear, and also leave you susceptible to falls and injury. Keylock ‘biners are usually a few dollars more expensive, but most climbers find this to be a very worthwhile feature.

Carabiner Gate Locks Overview

Many carabiners feature a locking mechanism on the gate that prevents them from coming open due to contact with another object or a fall. This feature is critical for use with rappel devices, and they help to add a level of peace of mind every climber is going to be sure to appreciate. While they’re heavier than non-locking models, it’s a small trade-off for most climbers.

There are two types of gate locks available.

Screw-Locks

The most popular option is the screw-lock. These models feature a locking mechanism which can be screwed upward to lock the carabiner and prevent it from opening. Most screw-locks are easy to operate with one hand.

Auto-Locks

Auto-locking models are the newest locking style available, and they make it even easier to lock your carabiner. As the name entails, these carabiners lock themselves in place automatically as soon as the gate is closed.

Carabiner Size & Gate Clearance Overview

The next consideration to make is the size of the carabiner. You’ll find models available in a seemingly endless array of sizes, and each different size is applicable for different functions. In general, the larger the ‘biner, the easier it is to clip and use. But, they’re also heavier and take up more room.

Most climbers try to keep a wide range of sizes with them, so they’re covered for virtually every application. Perhaps even more important than size is the gate clearance of a carabiner. This measurement refers to how wide the gate can open when clipping. A wide clearance of 20mm or more can be helpful for HMS applications, but too much clearance can make it more difficult to clip.

Carabiner Weight Overview

Serious climbers are always looking to shed weight wherever they can, and even though carabiners are all relatively light, every ounce counts when you’re on the mountain.

Unfortunately, there are some caveats with achieving a lighter weight. Many ultra-light carabiners used by hammocks, are made narrower to achieve lighter weight, and this can add unnecessary stress to your rope and result in a shorter lifespan for the rope and also the carabiner.

Carabiner Strength Overview

The last thing you’ll want to consider is the strength of the carabiner. Carabiner strength is rated in kilonewtons, and it’s measured along the lengthwise and widthwise axis. Strength is also measured when the carabiner is open.

All climbing carabiners must pass strict guidelines put forth by CE and UIAA, so you can rest assured that any carabiner that’s built to these standards is going to be strong enough for anything you’ll need to use it for. But, strength can be a great way to make a final decision on a carabiner if you’re having trouble deciding between a few different models.
