Factors to Consider When Choosing a Locking Carabiner

Best Locking Carabiners - Factors to Consider When Choosing a Locking Carabiner

When choosing a locking carabiner for rock climbing, it is important to consider factors such as strength and durability, size and weight, gate type, locking mechanism, and price. Read on to discover how these factors can impact your climbing experience.

Strength and durability

Choosing the right locking carabiner for your climbing needs hinges crucially on strength and durability. These vital features ensure longevity and robustness, even in taxing climbing environments. When choosing a carabiner, consider its strength ratings and ensure that it meets the requirements for your intended use.

The strength of carabiners is typically measured in kiloNewtons (kN).  One kiloNewton is equal to approximately 225 pounds of force. Carabiners are rated for strength in different scenarios:

  1. Major Axis Strength: This refers to the strength of the carabiner when it is closed and loaded end-to-end. The strength rating on the major axis can range from 23-24 kN. The minimum strength for most carabiners rated for climbing is 20 kN on the major axis.
  2. Minor Axis Strength: This refers to the carabiner’s strength when loaded sideways. The minor axis strength is typically lower than the major axis strength, but specific values may vary depending on the carabiner model.
  3. Open Gate Strength: This refers to the strength of the carabiner when the gate is open. The open gate strength can be reduced by as much as a third of its full strength. The specific rating for open gate strength may vary depending on the carabiner model.

Carabiners are tested and rated according to industry standards, such as the UIAA (International Climbing and Mountaineering Federation) standard, which demands a static strength of more than 20 kN for climbing carabiners. 

Petzl or Black Diamond provide durable options tested for their reliability in supporting anticipated loads during intense ascents. 

Size and weight

For rock climbers, every ounce counts – particularly when it comes to outdoor climbing. Your focus should be on performance and safety, not the weight of your gear. However, there is often a trade-off between weight and durability, so the lightest option may not provide the strength you need so verifying load capacity is critical.

The carabiners you are considering may have very different weights. Wiregate models are the lightest–weighing around 19g to 50g. Unfortunately, locking carabiners tend to weigh more than nonlocking models, but that extra heft is a trade-off for increased climbing safety.

Consider your climbing style and terrain to determine which carabiners are best for your needs. Once you know what you need, you’ll be able to find carabiners with the right balance between size, weight, and durability for your climbing needs.

Gate type

Choosing the right gate type for locking carabiners is another crucial factor to consider. The design of a carabiner’s gate influences its lightness, and compactness, and the important consideration of how easily it can be unlocked.

Non-locking models are lighter in weight and simpler to use and each style has unique features tailored towards different climbing situations.

If you’re into sport or alpine climbing, wiregate carabiners with their lightweight design and smooth operation are a good option. On the other hand, bent-gate variants enhance ease when clipping or unclipping ropes and gear, another critical factor for climbers.

Balancing these attributes with your personal preferences will help you choose a carabiner that fits perfectly into your climbing equipment portfolio.

Locking mechanism

Choosing the right locking mechanism for your carabiner is crucial when it comes to rock climbing. Several types of locking mechanisms are needed, including screw gates, double action, and auto-locking mechanisms.

Screw gates are the most common type and involve manually screwing a sleeve over the gate to secure it. Double-action locking carabiners have an additional feature that requires two separate actions to open the gate, providing added security.

Auto-locking mechanisms automatically lock the gate as soon as it closes, ensuring easy one-handed operation. 

When selecting a locking carabiner, make sure to consider which mechanism suits your preferences and needs best.


Another important factor to consider, of course, is the price. While investing in quality gear is crucial, especially for activities like climbing, you also want to find carabiners that fit your budget.


Can I use any carabiner for rock climbing?

No, not all carabiners are suitable for rock climbing. Using specifically designed locking carabiners that meet safety standards and have appropriate strength ratings to handle the forces encountered during climbing activities is crucial.

What are the main features to consider when choosing a locking carabiner for rock climbing?

When selecting a locking carabiner for rock climbing, it is important to consider factors such as the shape (D-shaped or pear-shaped), gate type (screwgate, twistlock, or autolock), weight and strength ratings, as well as any additional features like keylocks or anti-snag noses.

How do I properly lock a screwgate carabiner?

To properly lock a screwgate carabiner, you need to twist and tighten the gate until it reaches its fully closed position. Ensure that the twisted gate aligns with the keylock notch on one side of the biner body for secure locking.

Are there any maintenance tips for prolonging the lifespan of my locking carabiners?

Yes! To extend the lifespan of your locking carabiners, regularly inspect them for signs of wear or damage. Keep them clean by removing dirt and debris using mild soap and water. Avoid exposing them to harsh chemicals or excessive heat, and store them in a dry place away from direct sunlight when they’re not in use.

Final Verdict

After thorough research and testing, the top two recommendations are the DMM Shadow KWIKLOCK and the Black Diamond RockLock Screwgate.

The lightweight design, durability, secure locking mechanisms, and positive customer reviews make these carabiners stand out among the rest. 

So if you’re ready to take your rock climbing adventures to new heights, don’t forget to equip yourself with these reliable and high-quality locking carabiners!
