How to Choose Carabiner for GriGri

best locking carabiner for grigri

Many carabiners are available in the market, but not all can be paired with GriGri. To guide you in choosing a suitable carabiner, we have listed several factors you can consider before buying the product.

Locking mechanism

How the carabiner will secure is an essential factor to consider. The locking system of the carabiner is vital for the safety and protection of the climber. There are several locking mechanisms, but the screwgate is widely used.

Other locking systems include double-action, triple-action, magnetic, and twin gates. Each of them offers advantages and disadvantages. It is up to you to know the best one for you to maximize your safety.

Construction Materials

The materials being used determine the strength and durability of the carabiner. When choosing, it is better to look for one made with steel. Steel-made carabiners provide strength and durability but are heavier.

For climbers that do not want heavy carabiners, aluminum-made products will suit them. Aluminum is light and prevents the rope from rubbing and wearing down the carabiner, especially when using GriGri.


The carabiner’s strength is also essential, primarily if it is intended to be used with a Grigri. It is a must for you to look for a carabiner that is tested and certified by the CE or the UIAA. When a carabiner is certified, it is strong enough to handle the weight it carries during the climb.


The design of the carabiner is also essential when pairing it with a GriGri. They come in different shapes and sizes, but for GriGri, the D-shaped carabiner is the best one. It will help prevent the carabiner from rotating while shifting the load to the carabiner’s spine and not on the gate.

The primary reason for using the suitable carabiner for GriGri is to eliminate cross-loading issues. This situation is when the carabiner is stretched horizontally on its minor axis. One side of the rope stresses horizontally against the gate, the locking sleeve, the nose, and the center of the spine.

Since a carabiner is designed to be loaded on the longer axis near the spine, it will be weaker once cross-loading happens. So, it is a must to look for a carabiner that prevents this issue when using GriGri.

Petzl, the creator of GriGri, recommends using D-shaped carabiners to be paired with their belaying device. If not, the company is recommending their Freino design. More importantly, using a locking carabiner fits well with a GriGri regardless of its type.


To prevent cross loading during the climb, using the most suitable carabiner for GriGri is essential. Using standard carabiners will not prevent the situation from happening. A specific carabiner intended for Grigri is the best thing you can do if you want to eliminate the chance of cross-loading during the climb.
