Not all rock climbing carabiners are created equal. Learn the basic differences between the carabiners and become a safer climber.
There is nothing quite like staring at a brand new and shiny carabiner. The coolness of the metal against the skin, the sheen coming off its surface, and the rock climbing adventures it suggests all contribute to the unique experience of picking out and buying a new carabiner for that next epic rock climbing outing.
As much as it can be an emotional experience, picking out the right kind of carabiner should also be a precise science. First of all, the purpose of the carabiner has to be determined before the right type of carabiner can be purchased.
Common Uses of Carabiners
In general, carabiners can be used for:
- clipping into rappel anchors or a belay.
- clipping the climbing rope into a quickdraw while lead climbing.
- rigging a belay or rappel device.
- carrying gear on a harness or gear sling.
Carabiners also come in various forms and sizes. An oval shaped carabiner is most often used for racking gear and aid climbing. However, since it puts equal stress on the spine and gate of the carabiner, strength is sacrificed. The D-shaped carabiners amend such a weakness by centering the force onto the spine of the carabiner, thus increasing the strength. Other pear shaped and asymmetrical shaped carabiners allow for a bigger gate opening for easier rope clipping.
The next thing to look out for is the type of gate the carabiner has. The gate is the opening part of the carabiner which rests on a hinge. This is the most crucial design of a carabiner since a carabiner with the gate open has a greatly reduced strength, often down to only a third of its closed gate strength.
A solid gate carabiner has a straight and solid metal gate. This type of design is great for just about anything and is often times used on a quickdraw as the clipping end onto a bolt.
A bent gate carabiner also has a solid metal gate, but it is slightly bent towards the spine of the carabiner. This type of gate allows for easier clip in of the rope. On a hard redpoint attempt when every millisecond counts, a bent gate carabiner can be the difference between eternal glory and another failed attempt.
Wire gate carabiners are lightweight and also very strong. They are also easy to clip. On a long multi-pitch route requiring a lot of gear, the ounces that using wire gate carabiners can shave off can often lighten up the load significantly.
Locking Carabiners are Essential for Safe Climbing
Carabiners can also come with locks to prevent the gate from accidentally opening and unclipping. These locking carabiners are critical when clipping into belay or rappel anchors. Whenever a climber is setting up any kind of anchor, locking carabiners should be used to make it fail-proof. The carabiner used with a belay device should also be of the locking variety to ensure the safety of the climber. Read here our hands-on review on the best locking carabiners on the market.
Choose the right carabiner for the right situation can increase the safety margin of a climb. Since the sport of rock climbing is inherently dangerous, knowing the best way of using rock climbing equipment greatly reduces the chances of accident due to human error.
