In pictures, it looks awesome when you see climbers who were able to reach the top successfully. Their strength, willpower and knowledge of climbing and safety gives them the utmost edge to achieve that. Of course, it will not all be possible without the huge help of using some of the best and strongest outdoor climbing gears out there.

Aside from the sturdy ropes and harnesses, your climbing experience will not be complete without the carabiners. If you will use ropes and go outdoor climbing, you need to have these carabiners to be successful on your activity. These metal loops with a gate lets your rope pass through it. When the gate is closed, you now have a closed loop which creates a secured rope. They are an important piece in climbing.

It is important to know the anatomy and function of carabiners. They are attached to the rope and to pieces of gears which provides for safer climbing experience. They are usually made of aluminum or even of heavier steel to ensure its sturdiness. Their shapes can differ, but it is usually elongated triangle or oval, with an opening gate on one side so you can easily clip and un-clip the other gears. Know that there are two main types of carabiners, the safer “screw gates” and the simpler “snap gates”.

This information can help you decide which of the best and strongest climbing carabiners you are going to get for your successful climbing activity.
