Best Carabiners Buyer’s Guide

Material & Durability

For carabiners, aircraft aluminum alloy is a good choice because it is lightweight and rust-resistant. It also has a weight rating of 25KN (5,620 pounds), which makes it great for use outdoors. These carabiners are also ideal for Master Points on top rope anchors for climbing.


The shape of a carabiner can have a significant impact on how it works. Our most popular carabiner type is the asymmetric D carabiner and the D-shaped carabiner with a straight, bent, or wire gate. These carabiners have a wide gate opening, making it easier to clip and close with one hand. They are also easier to apply the load on its major axis, which is where most of its weight rating is retained. Keep in mind that none of our picks come in a pear shape.

Locking Mechanism

Three locking carabiner mechanisms are wiregate, spring gate, and screw lock. Wiregate and spring gate carabiners are easy to use but have a low weight rating. Screw lock carabiners have a higher weight rating and are less likely to open accidentally.

Number/Type of Certifications

The CE and UIAA certifications mean that a carabiner has been tested by a safety governing body, and it has been proven to be strong and hold a certain weight. It gives us confidence that the carabiner will work as intended without snapping.

Ease of Use

When looking for a carabiner, find one with a spring or wire gate. It will make it easy to open and close without having to screw and unscrew the lock. The gate should also move at least 60 degrees so there is enough clearance.

How to Choose Carabiners

There is a wide variety of sizes and shapes of carabiners, and the one you choose will depend on what you want to do. Different climbing activities need different sorts of carabiners. You must first grasp the distinctions between them to make an informed decision and apply them correctly. The following are three key things to think about:

  • Shape

  • Gate type

  • Size, weight, and strength

Think about your needs when you understand the differences. You will need to consider what type of climbing you do and how you will use the Carabiner.

Pear Shape

Pear-shaped carabiners have wide gate apertures, similar to the asymmetric D shape, to make it simple to clip ropes, knots, and equipment. They can be used at anchor points for top roping or multi-pitch climbing, but their main uses are for belaying and rappelling. These are called HMS carabiners; some even bear the HMS logo on their spines. According to HMS, the Carabiner has a broad, symmetrical top that complements a Münter hitch.


  • extensive gate opening
  • Mainly made for belaying and rappelling


  • Most other shapes are heavier and cost more.
  • Not as strong as a D or an asymmetric D.

D Shape

D-shaped carabiners are suitable for most kinds of climbing. They hold the weight off-center towards the stronger side. It makes them stronger than oval carabiners, even though they are smaller and lighter.


  • most durable shape
  • more excellent gate opening compared to an oval form


  • heavier and with a smaller gate opening than an asymmetric D shape
  • more costly than an oval shape

Oval Shape

Oval carabiners are a versatile and affordable option. They’re not as strong as other shapes but offer more gear-holding capacity than D-shape carabiners. Oval carabiners are also symmetrical, which makes them ideal for use in rappelling.


  • The consistent shape prevents load shifting
  • It has more gear than D-shape carabiners that you can hold


  • heavier and with a smaller gate opening than other forms
  • weaker than other shapes

Straight Gate Carabiners

Straight gates are robust, practical, and simple to use. They are widely available and helpful for a variety of things. Carabiners with straight gates can be found on quickdraws, and they are often used to rack gear such as cams and stoppers. As the name suggests, they are straightforward from pivot point to end. They are spring-loaded like most other varieties, allowing for simple opening when pushed and automated closing when released.

Some keylock carabiners are also straight-gate carabiners. A keylock carabiner features a smooth notch where the nose of the Carabiner and the gate converge. It prevents the Carabiner from irritatingly catching on your harness gear loop, bolt hangers, and other slings. This feature will probably cost you a little more, but it’s a wonderful addition.


  • robust and simple to utilize
  • It has a keylock nose that allows for snag-free clipping


  • Heavier than the wire gate

Bent Gate

These gates are strong and can be easily clipped onto a rope. They are usually used for quickdraws.

Just like straight-gate carabiners, some bent-gate carabiners can also be keylock carabiners.

Bent-gate carabiners typically have an asymmetric shape, making them easier to open than other types of gates.


  • Make it simple to clip the rope, Durable

  • It has a keylock option for snag-free clipping


  • Heavier than the wire gate

Carabiner Size, Weight, and Strength

Carabiner Size

Carabiners are available in a variety of sizes. Larger carabiners are generally easier to handle and clip (they have larger gate openings) and can hold more gear inside. They’re typically utilized with belay and rappel systems. Smaller carabiners may be more challenging to clip, but they are lighter and take up less room on your rack.

You might wish to consider the open gate clearance while examining the size of a carabiner. This number tells you how wide the gate can open, plus the depth and shape of the bottom of the Carabiner below the gate. Generally speaking, smaller carabiners have less clearance.

You don’t want the gate too close to your finger, or it might get stuck. But you also don’t want it to be too deep, or it will be difficult to clip the Carabiner onto something. You want just enough clearance so that it is easy to clip.

Carabiner Weight

Generally speaking, the less weight you carry when climbing, the better. But lighter carabiners are not always the best choice. The smaller size of superlight carabiners can make them more challenging to use when fastening a bolt or rope. Additionally, they frequently have lower lifespans and worse gate-open strengths. Since the narrow ends can act as edges and wear away at your weighted rope as it slips through, narrow carabiners can also result in greater rope wear.

Carabiner Strength

Carabiners are rated for their strength in different directions. The ratings are usually marked on the spine of the Carabiner. Carabiners that meet UIAA and CE standards are plenty strong, as long as you use them correctly. The gate-open strength and minor-axis strength can vary among different carabiners. 

You might use strength ratings when looking for a carabiner for climbing. Find the carabiners you like, then look at the strength ratings. The one with the highest rating might be the best one for you. Remember that smaller and lighter carabiners are usually weaker than bigger, heavier ones, but this is not always true. 

Gate lash is when the dynamics of a climbing fall reduce the overall strength of a carabiner, making it more likely that the Carabiner will break. It can happen when:

  • The inertia of a gate overpowers the spring pressure holding it in place.
  • A gate runs into another thing.

Use carabiners with certain gate designs, such as a wire gate, to protect against this type of failure. You could also choose carabiners with locking gates or high gate-open strengths. Get recommendations from an experienced REI salesperson.

Which Carabiner To Use

Consider your intended use of the carabiners after learning how shape, gate type, size, weight, and strength affect performance.

A carabiner’s strengths for one sort of climbing may not be its strongest suits for another. For example, a small wire gate carabiner might be good for attaching gear to your rack or making lightweight trad quickdraws. However, this Carabiner might not be as easy to clip as a larger, heavier carabiner.

Most seasoned climbers favor carabiners with a particular gate style, size, and shape. Here are some general suggestions for that just starting: 

Use of the Carabiner

  • Rope climbing and belaying hefty locking carabiner in the form of a pear
  • Quickdraws for sport climbing Asymmetrical D carabiners with wire gates, bent gates, or straight gates
  • Climbing-specific quickdraws wire gate-equipped asymmetric D carabiners
  • Stacking traditional equipment Oval, D, or asymmetrical carabiners

When looking for a carabiner, it can be helpful to go to a local REI or another climbing shop. You can try out different models and see how they feel in your hand. Test the ease of clipping and unclipping the carabiners, as well as the efficiency of the gates. To lock the carabiners, try locking and unlocking the gate several times (with one hand). Select products that are comfortable to use run smoothly, and are simple to maintain.

Frequently Asked Questions About Best Carabiner

Does Carabiner Shape Matter?

Different carabiners have different shapes. People might prefer one shape, but that doesn’t mean it’s the best for every situation. Certain shapes are better for particular tasks.

What Is a Belay Carabiner?

Pear-shaped carabiners are used for belaying, rappelling, and anchoring. People also use them for top roping and multi-pitch climbing. You might hear these called HMS carabiners because they have the letters HMS on the spine.

Can You Climb on Belay Loop?

The belay loop is very strong and can hold a lot of weight. It is also very safe. The only problem is that it can wear out over time. Because it rotates, you won’t wear it in one spot for very long.

How Strong Should a Climbing Carabiner Be?

The UIAA standard for climbing carabiners demands a static strength of more than 20kN. This value is much stronger than needed to hold a person’s weight in a worst-case fall scenario.

What Is a Belay Device Called?

Assisted-braking belay devices help the belayer catch and hold a fall. Your protection will be ensured by the safety equipment that locks onto the rope if an unexpected force is applied to it.

How Many Carabiners Are Needed for a Top Rope Anchor?

You’ll want to have at least three anchors when you’re outside. You can use them for different things, like rigging a ground anchor or a rappel backup. But remember that some anchors, like small D and modified D-shaped locking carabiners, aren’t as good because they don’t have a large gate opening. That means it will be harder to clip bulky knots and masterpoints.

What Type of Carabiner Locking Mechanism Is Suitable for Rope Access?

There are two types of gate carabiners: solid and wire. Solid gate carabiners are easier to use, while wire gate carabiners are easier to clip a rope into. Bent-gate carabiners are especially easy to clip a rope into, making them ideal for quickdraws and alpine draws.
