How Do I Choose the Best Carabiner?

Exploring the vertical world is one of those activities where you need to have immense faith in the gear you carry, be it climbing harnesses, climbing helmets or carabiners. That’s because your life is on the line!

Carabiners are everywhere—you see people hanging keys and water bottles off them, but that is not what they were originally designed for. Conceived by the German climber Otto Herzog, ‘biners allow climbers to rack gear, and clip climbing ropes for the much-needed protection.

Owing to advances in design and metalworking, these accessories are available in a myriad of shapes, designs, models and colors . There are different types of carabiners designed for different purposes, so read on to find out which one is right for you.
Price
Truly, this section shouldn’t even be here, because it’s a lifesaving device that we’re dealing with. Would you go out and buy a poor quality canopy for a tandem? Hopefully not! Google “cheap bungee jumping carabiner” and voila, at least at the time of this writing, there were no "real results" in terms of ones designed for heavy duty use since this is not a place to cut corners! You can, however, buy an inexpensive carabiner (aka cheap carabiner) if you’re looking to carry along a water bottle, but you shouldn’t if you’re going to be doing a tandem or tethering Max’s leash.

Even though these premium safety devices are worth their weight in gold, they do not cost anywhere near that. To give you a rough idea, the price of a carabiner depends on its design and size, and could range from $10 to over $50. ’Biners are also available in sets of 5 or 10, which could spike up the price, but they are worth it since you should be carrying more than one anyways regardless of the activity, and buying them separately can lead you to spending more in the long run.
Features
Whether you’re taking Max for a walk or exploring ice formations, you’ll want to buy a carabiner that won’t let you down, so consider the factors below when on the shopping trail.
  • Shapes – Different types available such as pearl or oval; the one you choose will dictate how you’re use it.
  • Materials – Mostly made from durable materials such as steel and aluminum, both being lightweight and hard to break.
  • Gate Type – This is what will open and close the carabiner.
  • Gate Closure – The way the gate attaches to the carabiner
  • Gate Clearance – This is the size of the opening when the gate is unlocked.
  • Nose – This is the part of the gate that the nose snaps into, where some feature a shroud to prevent them from opening.
  • Weight – Recent technology has made biners extremely lightweight, but take note that every ounce counts when exploring peaks.
  • Size – large ’biners offer bigger gate clearance and hence can carry more gear and are easier to handle.
  • Strength – Rated for three different spine strengths, and measured in measured in kilonewtons, or kN, where each is equal to roughly 224.8 foot-pounds of force.
  • Locking vs. Non-Locking Gates – Common options are straight gate, bent gate and wiregate carabiners.
  • Brand – Needless to say, carabiners are crucial pieces of safety gear, so look for trusted brands to achieve peace of mind.
Construction and Design
When it comes to construction of carabiners, material plays a crucial role. Steel and aluminum top the list as common carabiner materials. Consider steel carabiners for situations that are susceptible to more abrasion, such as rope anchors in dusty environments. Keep in mind, though, that steel ’biners are heavier and more expensive than their aluminum counterparts, so consider this before making your purchase. Aluminum-made carabiners are a great choice for other situations, with some being forged using cold or hot processes to enhance strength and durability and others are anodized so that they can be dyed different colors.

The next thing you need to determine when shopping for the best carabiner is the shape that is appropriate for your needs. To briefly explain, asymmetrical D-shaped carabiners are the most popular design of all, and are a preferred choice for climbers owing to their strength and large gate opening. Regular D-shaped ’biners are smaller and feature a larger gate opening than their asymmetrical cousins, and are also a great choice for most types of climbing. Pear-shaped ’biners generally also have large gate openings to allow easy clipping of gear such as ropes and knots. Although they can be used for multi-pitch climbing and top roping, their best use is for belaying and rappelling. Some pear shaped carabiners are embossed with “HMS” on their spin, which indicates that they feature a wide top, a selling point if that is something you are looking for.

Furthermore, you will have to choose between the many gate types. To break it down for you, straight gate carabiners are easy to use and are commonly bought for a variety of purposes, and as the name reveals, are straight from pivot point to tip. Moving on, bent gate biners feature a concave shape, making them easy to clip onto a rope. Both straight and bent gate biners can feature a keylock for notch-less, hook-less and snag-free clipping. Wire gate carabiners feature a loop of stainless steel wire, and are usually fitted on larger gate carabiners.
Performance and Ease of Use
After you consider the material, shape and gate of the carabiner, size and weight should be given some thought for several reasons. Although most ’biners are pretty light, 20 of them will increase the weight of your climbing kit. In terms of size, it will of course affect the weight of the device, but also its function as small models are generally hard to clip. Most manufacturers either list strength of a respective device in kilonewtons (kN) or in the load capacity. Regardless, you should pay attention to these metrics, because it will determine the performance of the carabiner. Lastly, think how you will be using the carabiner—one may be great for one type of activity, but not recommended for another.
