Best Locking Climbing Carabiners Buying Guide
Before choosing the best locking carabiner you should consider following options:
1. Clip Strength: Carabiners are strong, but the clip is the weak link. Damage the clip and the carabiner is useless. The clip is what takes the abuse of being clipped to a harness and being used to clip a line to an anchor.
Look for a tough clip. Solid wire or solid-bar clips are the most durable. Wire clips are the lightest and easiest to clip.
2. Carabiner Size: Carabiners come in many shapes and sizes. Standard locking carabiners range in size from 8mm to 13mm.
Larger carabiners are easier to grab and hold more gear. Smaller carabiners are lighter and take up less space on a harness.
You may want two sizes to meet your needs. Small carabiners for clipping to a harness and larger carabiners for clipping gear to an anchor and for belaying.
3. Carabiner Use: Carabiners are used for many things. They are used for clipping gear to anchors and for belaying, but they are also used for many other tasks.
They are used for creating makeshift bridges, for making an A-frame, for getting over an obstacle, and for many other things. Be sure the carabiner meets your needs.
4. Gate Fit: The gate fit, or how the carabiner opens and closes, is important. The smoothness of the action, or how easy it is to open and close, and the amount of force needed to open and close the gate are both important.
The amount of force needed to open and close the gate will depend on the type of carabiner, but they all have variations.
If the carabiner is too easy to open, there is a chance it will accidentally open and drop the rope. If it is too hard to open, then it may be difficult to clip and unclip the carabiner.
5. Rope Damage: There are two things to consider when looking at how a carabiner will affect the rope.
First is the amount of friction caused by the carabiner. If there is too much friction, then it will be hard to clip and hold the rope.
The second is the wear on the rope. If you are clipping a line over an edge, then the carabiner will rub against the edge and cause wear.
This can cause the rope to fray before the end of the rappel. If it will be used over an edge, look for a carabiner that is designed not to cause damage to the rope.
6. Gate Types: There are many types of gates on carabiners. There are three main types; wire, solid, and hybrid.
Wire gates are the lightest and easiest to clip. They are great for quickdraws and clipping to a harness.
Solid gates are very durable and give a smooth action. They are great for belaying and rappelling.
Hybrid gates are a combination of wire and solid. They are great for clipping and unclipping and for many other uses.
7. Gate Location: The location of the gate affects how the carabiner will be used.
If the gate is on the top, it will be easier to clip a line over an edge. If the gate is on the bottom, the carabiner will be used mostly for belaying.
Pick the orientation that best fits your needs.8. Cost: Carabiners come in
