Best Climbing Carabiner Buying Guide
The need for a carabiner is manifold, and so it is equally very important to keep the necessary features in mind. And that is not always the easiest of the jobs. You need proper knowledge and guidance to buy the right carabiner for yourself. This is what we will discuss here in this buying guide, this and much more.
We have discussed the features and multiple things like the workings of the climbing carabiner in this section. After this, you can purchase the right climbing carabiner yourself and even recommend some for your friends. You will be conversationally fluent in the working of the climbing carabiner and its features.
Let’s make you all that and start with the buying guide.
A carabiner has many parts on carabiners. While the designs may vary widely, the structures come with the same parts. If you want to know what the carabiner is worth, you need to read this part.
There is the spine. It is the strongest axis of the carabiner; the spine carries most of the weight and force while climbing.
Then there is the nose. The nose is the connecting part of the carabiner that connects the spine with the gate and the rest of the ensemble.
The gate is the part that opens and attaches the rope. This is a spring loaded gate, and it opens inwards. You can attach ropes, devices, or pieces that are used to hang any object.
The rope basket is the bend where the rope gets put. This area is a wider, large basket to allow rope movement, thus reducing wear to the carabiner.
The runner end is the bend in the bottom. This is the part that is used to help position the carabiner to allow quickdraws or harness.
Climbing Carabiner Material
There are two main materials that climbing carabiners are made of. Both have some great advantages and disadvantages to them.
I. Stainless Steel Climbing Carabiner
Stainless steel carabiners are extremely durable and long lasting. But these are relatively heavier for climbing. Steel carabiners are seldom used for climbing; these are mostly dedicated for heavy use situations like gyms and anchor points.
Steel carabiners have a higher weight capacity, and so they last longer. They are wear resistant. But they are on the higher on the price, and weight. Many people prefer both on the lower side.
II. Aluminum Climbing Carabiner
Aluminum makes lightweight carabiners and very durable climbing carabiners. You can use the aluminum carabiner for years on end. These will serve you for a long time, almost as long as the steel carabiners. The strength of the aluminum carabiner is almost equal to the steel carabiner, but the aluminum carabiner comes at a lower price point.
Climbing Carabiner Strength
Every climbing carabiner manufacturer is legally required to have the strength capacity rating on the back internal spring bar and packaging. This way, the customers can figure out if the climbing carabiner is the one they need.
There are three major categories mentioned. Lengthwise or major axis, sideways or minor axis, and open gate.
But there is an easier way. As long as the climbing carabiner meets the EN 12275, the European Standard, or the UIAA standard, it should be okay for your use. It would be better if you looking for the CE and/or the UIAA icons on the spine of the carabiner. If the climbing carabiner has that or those, you can be assured that this is the standard carabiner for you.
The CE or the UIAA standard means the carabiner has-
- Major Axis 20 kN
- Minor Axis 7 kN
- Open Gate 6 kN
Some climbing carabiner brands come with the standards laser etched on the sides. While this should not be the only criterion for climbing carabiners, this can be the tiebreaker for you if you have trouble choosing two carabiners for your intended purpose.
Climbing Carabiner Shape
There are many different shapes of the climbing carabiner that are available on the market. These climbing carabiner shapes allow certain advantages and have some disadvantages too.
We will see what the shapes are and what they are good for in this section.
i. D shape
D shape carabiners are the most common types of carabiners on the market around the world. These climbing carabiners are second to none, hands down.
These carabiners hold the load toward the stronger, non gated side, which is off center. These carabiners are smaller, lighter. These are the strongest shapes, with a large gate clearance that can hold almost all types of rope and objects.
ii. Asymmetric D shape
Asymmetric D shape is also the most popular design climbing gear on the market. These are also called offset carabiners or modified D carabiners. These carabiners work like the Regular carabiner, but they are very lightweight because they use less material and are smaller on one end. These carabiners can also have wide gate clearance, like the regular D shape. This makes the clipping easy on both the regular D shape carabiner and the asymmetrical D shape carabiner.
These are the most famous carabiner among climbers for climbing protection.
iii. Pear shape
Pear shaped carabiners are also a very common and popular carabiner among climbers around the world. This carabiner also has large gate clearance like the Regular D shape carabiner and Asymmetrical D shape carabiner and hence is very easy to attach ropes to. The Pear shape carabiner is perfect for clipping ropes for climbing, knots, and gear loop.
The pear shape carabiner can be used for anchoring, which is why this is sometimes called HMS carabiner and comes with HMS written on the spine.
The pear shape carabiner is a perfect belay device and rappelling device. This is heavy and priced heavily than other shapes. These work perfectly well with a Munter hitch.
iv. Oval Shape
Oval carabiners are the original, traditional style typical carabiner. These are the most common types of the carabiner in the world.
Oval Shape carabiners are the most versatile carabiners.
The oval carabiner is shaped for limiting load shifting and for smooth and wear free use. These are the ideal carabiner for climbing because they use the curves to center the load where the carabiner is the strongest.
However, these carabiners have smaller gate clearance and are heavier than other shapes.
Carabiner Gate Styles
There are two major gate styles on the climbing carabiner. These are used for building anchors for climbing. We categorize the gate styles in two styles; each has its own subcategories as well.
a) Non Locking Gate
Non locking gate has quick access to clipping ropes and other things. These are more popular for quickdraws, climbing protection, racking protection, and climbing shoes. There are many types of non locking gates.
b) Solid Gate
A solid non-locking gate is made with a solid piece of metal, aluminum, or steel, depending on the primary material of the carabiner.
The gate opens at the nose and connects at the hinges of the carabiner. These are the most common carabiner gate types and are used in climbing sports for their quickdraws. You can use these gates for keeping the clipping bolts plates because these are less likely to wiggle free when climbing.
c) Wire Gates
These gates use a loop of wire made of durable materials such as aluminum. These are the preferred gate types for lightweight carabiner because it doesn’t add up much weight. These allow alpine quickdraws and are perfect for camming devices.
Wiregate carabiners may look light and weak, but it is less likely to open accidentally. These are very reliable in that regard.
Both solid and wire gates are available in the straight and bent gates. Straight gates are often used on the bolt end of quickdraws and for racking protection. The bent gate focuses on the ergonomics of pulling a rope through the carabiner, making the bent gate much easier to attach a rope to a quickdraw.
d) Locking Gates
Locking gate barrels are designed specifically to keep the gate closed for protection. These locking gate carabiners are used for anchors, belay devices, and other climbing protection equipment.
There are many types of locking gate climbing carabiners.
a. Screw lock
The most common and popular type of locking style in climbing carabiners is the screw lock carabiners. These are very simple, easy to use, durable, reliable, and cheap. There is a threaded barrel that is screwed. This allows you to lock or open the screw gate easily.
Screw gates are reliable because there is no chance of the lock unscrewing by itself. It is always locked and gives added security. You always need to be vigilant and check the screw gates lock before you start using the climbing carabiner to avoid accidents.
b. Twist Lock
The twist lock uses a spring loaded mechanism that results in locking the carabiner shut easily and safely. These auto locking carabiners are reliable and convenient but are prone to damage from weather conditions. The spring can be damaged with dirt, dust, rust.
c. Magnetic Locking System
These are the modern popular auto locking carabiner systems that allow you to lock the gates with little to no effort. The gate comes with magnets that close the gate quickly and firmly. The gate stays in place as securely as possible that you need for your climbing protection.
d. Ball locking carabiner
These are similar auto locking carabiner system that allows you to secure the gates easily. There is a small ball that is pressed to open the gates of the climbing carabiner.
e. Dual gate locking climbing carabiner
These carabiners feature two opposing gates that open in opposing directions. They are a great option for your climbing protection needs if you are looking for a passive locking system. There is a triple-action gate too.
The nose is another most vital part of a carabiner. This is not so for the strength, but because of the functionality and the application.
There are several types of noses in climbing carabiners on the market.
I. Non Keylock nose
Non keylock nosed carabiners come with a notch in the nose that gets hooked on the gate. This keeps the gate securely held, and the gate stays closed under force or stress. These are the most common nose types on the climbing carabiner. These are cheap, simple designs, easy, and convenient to use. There is no nut or stopper. But that can be a downside of this nose type too.
II. Keylock Nose
Keylock, as the name suggests, has intricate patterns such as those found on the keys. The patterns, jigsaw pieces, and designs make sure that your carabiner doesn’t snag on a bolt or harness. These are premium quality features on a carabiner.
III. Hooded Nose
These locking systems come with the wire gate carabiners, mainly. A hooded nose hides the notch onto which the wire gets locked, which keeps the carabiner locked for your climbing safety.
There are three main sizes of the climbing carabiner. The sizes come at very convenient intervals for your needs; there is the full size, the small size, and the mini size.
The full size climbing carabiners are for people who choose to rack nuts, stoppers, hexes, or quickdraws with full size carabiners. These are perfect for people with bigger hands. Just because the size is full doesn’t mean the carabiner should be heavy. There are many lightweight options for full sized carabiners.
The small and mini sized carabiners are for light climbing or putting together alpine quickdraws or racking cams. These are also lightweight and are very reliable for use.
The use of a carabiner should also be a driving factor of the purchase. There are carabiners for different purposes. Knowing which carabiner works finest for what purpose can be vital.
i. Belay Device
Belaying is an important climbing tactic. And it requires a special belay carabiner. Many people have suggested using a small, asymmetrical D-shaped carabiner can make belaying harder. The perfect belaying carabiner is the HMS locking carabiner. These carabiners are popular, even in the HMS auto locking carabiner versions, for belaying. Some belay carabiners can capture the belay loop and prevent the twisting and cross loading across the gate.
ii. Belay building
Making a safe belay position is a very important skill. Asymmetrical D shape carabiners with screwgates are ideal for connecting slings or the rope for protection. But for the main hub, you will need a large HMS Locking Carabiner.
An oval shape carabiner is perfect for racking.
Quickdraws are made by joining two carabiners together by high capacity webbing. One point or the master point of the carabiner is connected to the point of protection, like a bolt hanger or a camming device.
Most climbing carabiners are made with aluminum, or 7075 aerospace grade aluminum. But the manufacturing can vary depending on the variables. There are two main types of manufactures.
Forging has been used for decades to make carabiners. Here hot aluminum rod is bent to make the carabiner. This makes the carabiner very strong.
Hot forging needs liquid of the material and heating the dice. This gives you a more tailored design.
This process allows aluminum I beam construction profile and enhances the performance.
After forging, aluminum or steel constructions can be anodized with a thick natural oxide layer. This oxide layer keeps the aluminum safe from air, water, and other harmful conditions. This also allows coloring the carabiner easier.
Care and Maintenance of A Climbing Carabiner
If you feel your carabiner feels a little stuck closed, the gate is slow to close and open, or you hear a noise while trying to open or close the gate, it is time to clean the carabiner.
You will need-
- An old brush
- Hot soapy water
What you need to do is-
- Submerge the carabiner inside the soapy water for 5 to 10 minutes. Remember, do not boil the water. Take water that has been boiled and cooled off to a warm level.
- Wearing gloves, brush the area around the carabiner gate.
- Once done, take the carabiner and put it on the towel.
- Use some lubricant, one to two drops, around the area of the gate and spring.
- Repeatedly opening gates a few times and making sure to wipe out the lube from the body is the last step.
