Carabiners are designed to quickly and securely connect two pieces of equipment or materials, like ropes, chains, or harnesses, in various adventure, safety, and industrial applications.

Carabiners come in various types, each tailored to specific uses. Common types include locking carabiners (with a screwgate or auto-lock mechanism) for added security and non-locking carabiners for quick and easy connections.

Selecting the correct carabiner depends on factors like the intended use, load capacity, gate type, and material composition. It's crucial to consider the application's safety requirements and match the carabiner's specifications accordingly.

Proper carabiner use involves regular inspections for any damage or wear, ensuring they're always loaded correctly on the major axis, and avoiding cross-loading to prevent accidental unclipping.
