As mentioned above, not all products are created equal, so it is important to keep in mind what you plan on primarily using the carabiner for. Some products aren’t designed to withstand higher amounts of weight and some are specifically designed for that. If you are planning on using it for climbing, or even hanging a hammock, you need to pay close attention to how many kilonewtons the product is designed to handle. It is also important to check and see if it is specifically designed to be used while climbing because, even though it may be able to handle the weight, the locking mechanism may not be strong enough, or safe enough to be used while climbing. Below is a list of the best 10 locking carabiners that keep all of these aspects in mind.

As you can see by looking at this list, each carabiner is made a little different. Some are made to withstand higher rates of force, while others are not. Some are made with screw locks or keylocks for added safety and security, while others are not. It is important to remember exactly what you intend to use the product for before you purchase it. This is especially important if you plan on using it for any type of climbing. The type of locking system it has, along with how much weight it can withstand will determine how safe it is to use for such activities. If you are unsure of what the product is designed for, you can always look at the product details to ensure maximum security and safety. This list was designed to help take some of the pressure off of finding that perfect locking carabiner and help you get on that right path to finding one that best suits your needs.

Criteria Used for Evaluating Best Locking Carabiners

Weight Capacity

Depending on what you are planning on using the locking carabiner for, it is important to check the overall weight capacity that it can tolerate. Most carabiners use the measurement of kilonewtons, which is how much force the product can handle. The higher the number of kilonewtons, the more force, or weight it can handle. Some products are designed to hold smaller items, such as keys and smaller bags or equipment while camping. These products have a lower kilonewton measurement, so they would not be able to withstand higher amounts of weight or any type of weight-bearing activity.

Other products are designed to withstand higher amounts of weight or force. These products have a higher kilonewton measurement. They are specifically designed to handle larger amounts of weight and force, such as hanging hammocks or climbing. Even though it may be able to handle a heavy load, it is still important to make sure that it was designed specifically for climbing, to ensure your overall safety.

Shape

The overall shape of the product also plays an important role in finding the perfect one that fits your needs. The shape can determine how large a gate, or opening, it has and how much you are able to hang from it. There are many different shapes out there, so it is imperative to find the one that best suits your needs. For example, if you are looking for a product that can hold more gear or items, then an oval-shaped product might work best for you. If you are looking for something with a larger gate opening, making it easier to manage and latch, then getting a D-shaped product might work best for you. It is always important to read the product details to ensure that you are getting everything that you need in a carabiner.

Locking Mechanism

The locking mechanism that a carabiner has is extremely important as well. Each locking system has its own perks to it, so it just comes down to what best suits your needs for your overall purpose of use. There are a few different types of locking mechanisms that you will see while you are out shopping and they are; screw locks, key locks, and automatic locks.

Screw locks are designed with extra safety in mind. With this kind of locks, you have to take an extra step in order to unlock your carabiner. It has to be screwed or unscrewed in order to unlock the device. This adds more safety and security while using the product and can generally be done with only one hand.

Keylock noses are also designed with safety in mind, but with an extra added feature. These types of locks are designed to be a little more challenging to unlock than a screw lock. They are actually more like a jigsaw puzzle, where you have to move it through a pattern to get it to unlock. These types of locks just make the product that much safer and can be unlocked in mere seconds once you get a better concept of the pattern and design.

Automatic locks are the easiest of the bunch. This is because all it takes to unlock this type of device is to simply push down on the mechanism unlock. These types of locking mechanisms are spring loaded, so they just simply snap back into place. They are generally used on carabiners that have a lower weight tolerance because the lock isn’t as reliable as the others mentioned above.

Material

The material that a carabiner is made from can play an important role in its overall durability. Most carabiners these days are made from either a strong aluminum alloy or solid steel. Although the solid steel is most likely the better choice when it comes to major weight-bearing activities, such as climbing, due to its more solid, sturdy design, don’t count out the aluminum alloy carabiners! The aluminum alloy carabiners these days are generally made from a strong aluminum that is used on aircraft, so they can be durable and reliable. It is still important to read the product details to ensure that you are aware of its intended use to ensure maximum safety.

Cost

As always, the cost of the product plays an important role as well. Whenever you are making an investment, no matter how big or small, you always want to make sure that you are getting your money’s worth and that your money isn’t going to waste. It is no different when it comes to purchasing carabiners. Whether you are just planning on using the product to hang smaller items, like keys and smaller bags, or using them for climbing or hanging hammocks, you will want to make sure that you are getting a high-quality product for a reasonable price.

The cost of a carabiner varies on a couple of factors, the first being the number of kilonewtons, or force it can withstand. The more durable products that are meant specifically for climbing and weight-bearing activities are going to be more expensive than those with lower kilonewtons. This due to the overall nature of use and the stability, durability, and longevity needed for these types of activities.  

Another factor that plays a role in the cost is the material that it is made from. Products that are made from aluminum or aluminum alloy tend to be cheaper than the products made from a solid steel. For example, if you are looking for the ultimate carabiner for rock climbing, you will notice that you will be paying a few more dollars for the solid steel product versus aluminum alloy because it is a much more solid and stable piece of metal.

FAQ

Frequently Asked Questions

 

Q: What is a kilonewton in reference to weight?

A: Most people think that the amount of kilonewtons has to do with actual body mass or weight it can hold, but they are wrong. It has more to do with force and gravity than anything else. For example, when you see a product that can withstand 24kn, it does not technically mean that it can hold over 5,000 pounds of weight. It means that’s the amount of force it can handle without breaking or bending. That is why it is so important to remember to check the product details to ensure its intended use and that you are getting the best one that suits your needs.

Q: What is the difference between a screw gate and a keylock nose?

A: Although they both focus on securely locking the mechanism in place, the main difference is how they latch and unlatch. A screw gate requires you to screw the lock into place, leaving little room for unintentional unlatching if screwed on correctly. The keylock actually takes the safety of the lock to a whole new level. Instead of just being an ordinary lock that you push in, it requires you to follow a specific pattern while you push in, allowing very little room for it to unlatch unintentionally, making it safe and secure for climbing.

Q: What do the terms, major axis and minor axis mean?

A: The major axis refers to the area where the weight is supposed to be distributed. This is the area that doesn’t include the gate. The major axis is designed to withstand the bulk of the weight as described in the product details. The minor axis refers to the part of the carabiner where the gate, or opening is. This part of the product is not designed to hold as much weight as the major axis but can withstand some amount of weight without causing the gate to pop open.
