Carabiners are a staple tool for any rope-intensive activities. The best example of these activities are climbing, rope rescue, caving, hot air ballooning, sailing, and any job that requires a person to work in high-altitude areas.

Most carabiners are made of both aluminum and steel. Climbing carabiner or sport those used in sports are usually lighter in weight compared to carabiners used in commercial purpose and rope rescue.

The harness of the climbers can be found somewhat adorned by varieties of carabiners; not for vanity but for necessity. A climbing carabiner can be considered as a lifeline of climbers, it holds and secures them during a climb. Due to this, the climbing community strictly insists on the usage of carabiners rated 20kN, manufactured and passed safety-critical system in load-bearing typically for mountain and rock climbing.

Divers use load-bearing screw-gate carabiners for connecting the umbilical cable to the air supply from the surface attached to the harness. This kind of carabiner for diving is usually rated for a safety load of 5kN or more.

Hot air balloons use carabiners for connecting the basket to the envelope, usually made of steel, and are rated at 2.5 t to 4 t.

But because of its popularity, there are carabiners that are made as key holders that are labeled as not suitable for climbing, these “mini-biners” or light clips did not pass the safety standards and load testing. Therefore, it is always best to read labels and confirm the appropriateness of the carabiner before using it.

The following are the best carabiners on the market.

How to Choose the Best Carabiner

Purpose

If you’re looking for a specific climbing sports carabiner, always go for tough, heavy-duty, and tested carabiners. It should be designed and made for the heavy demand of bearing load because, in these types of activities, your life is on the line. These built of carabiners are usually pricey compared to other carabiners in the market.

For multi-purpose use but requires heavy load duties, you may opt for strong carabiners that are made from sturdy materials like stainless steel alloy. Although it’s always best to have heavy-duty carabiners, one must still consider the value for money. If the carabiner does the job without having to spend a lot, that will be the best product to fulfill your needs.

Built

Carabiners come in different shapes, sizes, materials, and colors. It greatly affects the performance and function of the carabiner.

Shape

The D-shaped carabiners excel when it comes to locking anchor points and clipping protection. The design enables it to draw the force away from the gate in the direction of the carabiner’s spine. The D shape carabiner can be constructed lighter than other shape types, and the gate open is wider. Though this carabiner shape is tagged the strongest, it doesn’t mean that all D-shaped carabiners can withstand any force or heavy load.

The oval-shaped carabiner is probably the oldest type there is but still relevant for modern purposes. Because of its shape, this carabiner can be easily flipped. They are not as strong as the other shape type carabiners but their shape reduces shifting of the wights.

The pear-shaped carabiner excels when it comes to attaching belay devices. However, because of its shape, there’s a tendency of weight and strength drawbacks. But they compensate when it comes to the carabiner thickness. Still, it is the best shape option for your belay devices.

The asymmetrical d shape carabiners on the other hand have similar functions and designs as the d shape carabiner. The only difference is the wider gate opening because of its larger asymmetrical design.

Material

There are different metals used in constructing the carabiners. The lightweight kind is usually made from high-grade aluminum to maintain its weight while being sturdy at the same time. Heavy carabiners are usually made from stainless steel alloy but there are some heavy-duty carabiners that are made from a combination of aluminum and zinc.

For undemanding purposes such as key holder and water bottle clip, the carabiners are preferred to be light. The same goes with traveling, carabiners that are made to be light are very helpful for the users to not worry about the burden of carrying extra weight. Just be careful of sub-standard carabiner knock offs.

Locking Mechanism

There are 2 kinds of the carabiner locking mechanism. The non-locking carabiners are the following: straight gate, bent gate, and wire gate. While the locking carabiners are the following: screw lock and twist lock.

The most distinguishable difference between non-locking and locking carabiners is the weight. Locking carabiners are more dependable when it comes to securing the load. That why it is widely used for climbing. Non-locking types are often used for general clipping purposes.

Color

Some carabiners are available in different colors. Choosing the right color is fully dependent on your personal preference. But there are also carabiners that are made as plain as possible without any choice.

Strength, Durability, and Certification

To ensure that you bought the right carabiner suitable for your need, it’s best to check the certification and the product test result. There are different load tests, pressure tests, and force tests conducted to certify the rate of a carabiner.

The shape and materials play a big role in the carabiners’ strength and durability. But ultimately, the test will determine the strength and limit of your carabiners. Do not use carabiners above the limit load to avoid accidents.
