Top 10 Best Locking Carabiner

Things to Consider Before You Buy Your Best Locking Carabiners

Size of the Carabiner

Am pretty sure you know that carabiners usually come in different sizes, large and small. Large ‘carabiners are much easier to use and also easier to clip as a result of the bigger gate openings. Large ‘carabiners can also take hold of more gears within, and that’s why they are commonly used along with belay and rappel devices.


On the contrary, small ‘carabiners are much light-weighted and considerably takes up little room on your rack but then, they are rather hard to clip. Having this in mind will give you a better idea on the one to go with depending on your personal need.

​Carabiner Weight

I think you might also want to consider the weight of the carabiner you want to buy. Frankly speaking, when it comes to climbing, it is advisable to carry less weight. In other words,the lesser the weight that accompany you while climbing, my dear, the better for you. Overweight can make you slip and besides, you are way too high up on a tree of rock, so you really don’t need much weight while climbing.

However, if you decide to settle for lightweight ‘carabiner, then you should also bear in mind that lightweight ‘carabiners have narrow gate openings, not only that, their lifespan is shorter. Weigh your options and pick the one that interests you the most. I just thought you should know.

Carabiner Strength

Have you thought about the strength of the locking carabiner you want to buy? Did you just forgot about that? Ah! You shouldn’t at all. Knowing the strength of the locking carabiner should also be an integral part of your considerations. This determines the durability of the product, ensuring that it lasts long or not. The strength of these locking carabiners are measured or simply put, they are ranked in different angles;

the –LENGTHWISE-the major axis and SIDEWAYS-the minor axis.

Note that all climbing ‘carabiners have passed through checks by UIAA and of course CE standards. However, it is normal for some to be stronger than others.
