Buyer's Guide

best carabiners for climbing

The carabiners fundamentally differ in shape and gates type. Each type has its advantages and drawbacks, which furthermore narrow its use to specific purposes. Let's dive deep into the matter.

There are three main shapes of carabiners:

  • Oval carabiners
  • D-shaped carabiners *asymmetrical D-shaped carabiners
  • Pear Carabiners

Oval-shaped carabiners are the original carabiners, and what makes them an excellent choice is a tone space in the basket for racking gear. They are not quite popular nowadays, but they do hold more gear than D-shaped models and can be used for carabiner-brake rappels. As for the downsides, they are heavier and bulkier than other models but also more affordable.

D-shaped carabiners are the most popular type of carabiners. They are considered the most reliable model, despite their small size and lightweight.

Why is this so? Well, these carabiners have a lower basket and more massive gate, and what this means is that the load is kept at the strong side of the carabiner without the chance for moving to the weak side as it is with the oval ones.

Asymmetric D-shaped carabiners have even more gate clearance than the regular D-shaped and are lighter, which makes them number one choice for any kind of climbing, but they are the most expensive ones, as well.

Now, Pear carabiners have the best shape for belaying and rappelling as they have large gate opening for easy clipping of knots, ropes, well, basically any type of gear. Furthermore, they are heavier than D-shaped models and not as strong.

best carabiners for anchors

When it comes to the gate types carabiners have, we can differentiate four main gate types:

  • Straight gate
  • Bent gate
  • Wired gate
  • Locking gate

Straight gate carabiners are the most common ones, they are pretty strong and durable and most commonly used for racking gear and on quickdraws.

Bent gate models are also quite durable, and due to the concave shape, clipping a rope is way easier than with the straight gate ones, so they are reserved for the rope-end of quickdraws.

Now, wired gate carabiners are significantly lighter than the other two models as they encompass a steel loop of wire for a gate. But despite the popular belief, they are not weaker than other carabiners; in fact, they are less likely to freeze in the cold and reduce the magnitude and duration of gate flutter.

Within these unlocking types, there are two types of noses as well, the keylock style and the hook nose style. More preferable is the keylock style because, with the other method, the gear is likely to get caught in the hook.

As for the locking carabiners, they have gates that can be locked in a closed position to prevent the carabiners from accidentally open. They can either be manual locking carabiners or automatic.
