How do I choose the right carabiner?


Locking system

Carabiner locking systems can be manual or automatic. With manual systems (SCREW-LOCK), the sleeve must be screwed manually onto the gate to lock it.
It is recommended for carabiners that are only operated occasionally, like the main carabiner in a belaying station. Manual systems are also recommended for use in dirty environments where dust and dirt might interfere with the correct functioning of automatic locking mechanisms.

With automatic locking systems (BALL-LOCK, TRIACT-LOCK, TWIST-LOCK), the gate unlocks automatically. These systems are recommended for carabiners that are operated frequently, like carabiners linking a belaying or rappel system to a harness.

Picto Triact Triact-Lock System (TL) - Automatic locking system and triple action gate

  • Easy to use, even with gloves.
  • Prevents accidental openings once locked.
  • Available for the models Am’D, WILLIAM, OMNI and OK.

- Shape
Advantages:
• Rapid auto-locking.
Disadvantages:
• Sleeve must be unlocked every time carabiner is opened.
• Sleeve operation is fiddly especially with gloves, requires practice.
• Two hands are needed to insert a device into the carabiner.

- Safety
Advantages:
• Security of triple action locking (excluding rubbing and external pressure).
• Rapid auto-locking.
Risks:
• Chance of not locking properly when the carabiner closes (e.g. sling caught between the nose and the gate). The user must verify that the carabiner is properly closed and locked, even when using an auto-locking system.
• Sensitivity to mud or other foreign objects that can impede auto-locking.

Carabiner shape

The different shape of carabiners and making the right choice of carabiner shape will increase the ease of handling and safety for specific uses.

Carabiner shape has an impact on:
• major axis strength,
• load distribution,
• gate opening size, and capacity,
• strength in certain positions,
• ease of handling.

Another less obvious effect is the balance of the carabiner itself. For example, pear-shaped carabiners rotate more readily, which can result in poor positioning. D-shaped carabiners tend to stay in place better.

Petzl carabiners are available in three different main shapes, each designed for a specific use:

 D Carabiners

Asymmetrical D shape:
For attaching belaying and rappel systems, or for use at the end of a lanyard.

 

 

 

 

 

 


Pear shape:
For anchoring several ropes, slings or other devices, and to make rotating the knot easier when belaying with a Munter hitch.Pear Carabiners






 






Symmetrical oval shape:Oval Carabiners
For attaching belaying systems, pulleys, or gear. Prevents jerking when loading.
