If you’ve ever been on a climbing course and heard the instructor describe carabiners as “the most important piece of climbing gear,” you’re not alone. But many climbers have never thought to question why carabiners are such an integral part of the sport — after all, they’re the piece of gear that connects our rope to our belay device, so they must be necessary, right? It’s true that carabiners are a fundamental part of climbing, but the reason why is a lot more nuanced than the idea that they’re the most important piece of gear.
To help you select the best nonlocking carabiners for your needs, we’ve researched dozens of products and tested our top picks on real climbing gear.
Read on to find the best nonlocking carabiners for climbing.

Best Nonlocking Climbing Carabiners Buying Guide
Before choosing the best nonlocking climbing carabiners you should consider following options:
1. Use: Although carabiners are predominantly used in the climbing industry, they are also used in a variety of different industries, including the construction and real estate industries. Before purchasing new carabiners, you should determine the specific use of the carabiners to ensure that you purchase the proper ones for your needs.
If the carabiners will be used for climbing purposes, then you will want to make sure that they are manufactured from a durable material, such as steel. If the carabiners will be used in a non-climbing capacity, then you can purchase carabiners that are manufactured from a lighter material, such as aluminum.
2. Carabiner Type: Carabiners are typically manufactured from either a wire-gate or a snap-gate design. Wire-gate carabiners are typically stronger and more durable than snap-gate carabiners, but they do cost more.
Snap-gate carabiners are typically lighter and less expensive, but they are also less durable. If the carabiners will be used for climbing purposes, then you will probably want to purchase wire-gate carabiners, but if they will be used in a non-climbing capacity, then you can probably get away with purchasing snap-gate carabiners.
3. Carabiner Size: Carabiners are manufactured in a wide variety of sizes, ranging from extra small to extra large. Carabiners are typically labeled with a letter designation, followed by a number.
For example, a carabiner that is designated as a “C” is considered to be an “alpine carabiner,” which is used for climbing purposes. Wire-gate carabiners that are designated with a “7” are typically used in rigging applications.
In general, the larger the carabiner size, the stronger and more durable it is. However, larger carabiners are also typically heavier and more expensive.
4. Carabiner Stacking: Although carabiners are typically labeled with a letter designation, they are also typically labeled with a number designation. Carabiners that are designated with a “1” means that they are “single” carabiners and carabiners that are designated with a “2” means that they are “double” carabiners.
In order to make gear easier to find and organize, climbers typically use carabiners that are labeled with both a letter and a number designation. For example, a carabiner that is designated as a “C8” is considered to be a “double” carabiner.
Carabiners that are designated with a “2” means that they can be stacked on top of another carabiner. Carabiners that are designated with a “1” means that they can’t be stacked on top of another carabiner. If the carabiners will be used for climbing purposes, then you may want to purchase carabiners that are labeled with a “1” designation, so that they can be easily attached to one another when you are climbing. However, if the carabiners will be used in a non-climbing capacity, then you can probably get away with purchasing carabiners that are labeled with a “2” designation.
